when the value was too large (even for negative values)
(it should set -INF in such a case)
added: some missing methods for converting
for UInt<>, Int<> and Big<> classes:
uint ToUInt()
sint ToInt()
ToUInt(uint32_t &)
ToInt(uint32_t &)
ToInt(int32_t &)
ToUInt(uint64_t &)
ToInt(uint64_t &)
ToInt(int64_t &)
FromUInt(uint32_t &)
FromInt(uint32_t &)
FromInt(int32_t &)
FromUInt(uint64_t &)
FromInt(uint64_t &)
FromInt(int64_t &)
and appropriate constructors and operators
*** version for 64 bit platforms are not tested yet ***
added: double Big::ToDouble() /there was only Big::ToDouble(double &) /
uint Big::ToFloat(float &)
float Big::ToFloat()
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@316 e52654a7-88a9-db11-a3e9-0013d4bc506e
now ::FromInt can be used in place of ::FromUint
sample:
UInt<1> a;
a.FromInt(10); // previous was only: a.FromUInt(10)
changed: std::string Big::ToString(uint base = 10) const
std::wstring Big::ToWString(uint base = 10) const
can take optional parameter (base)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@315 e52654a7-88a9-db11-a3e9-0013d4bc506e
uint UInt::FromUInt(uint64_t n)
uint Int::FromInt(int64_t n)
void Big::FromUInt(uint64_t n)
void Big::FromInt(int64_t n)
and appropriate constructors and operators
added: TTMATH_FORCEASM macro
asm version of the library is available by default only for:
x86 and amd64 platforms and for Microsoft Visual and GCC compilers,
but you can force using asm version (the same asm as for Microsoft Visual)
by defining TTMATH_FORCEASM macro
you have to be sure that your compiler accept such an asm format
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@311 e52654a7-88a9-db11-a3e9-0013d4bc506e
bool UInt::IsOnlyTheLowestBitSet()
returning true if only the highest/lowest bit is set
added: uint Int::MulInt(sint ss2)
added: void UInt::Swap(UInt<value_size> & ss2)
void Big::Swap(UInt<value_size> & ss2)
method for swapping this for an argument
changed: small optimization in Big::Sub()
changed: now asm version is available only on x86 and amd64
(and only for GCC and MS VC compilers)
removed: macro TTMATH_RELEASE
for debug version define TTMATH_DEBUG macro
TTMATH_DEBUG is also automatically defined when DEBUG or _DEBUG is set
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@304 e52654a7-88a9-db11-a3e9-0013d4bc506e
when the argument was negative (they only returned 2)
added: some missing operators
UInt::operator~() /* bitwise neg */
UInt::operator&() /* bitwise and */
UInt::operator&=()
UInt::operator|() /* bitwise or */
UInt::operator|=()
UInt::operator^() /* bitwise xor */
UInt::operator^=()
Big::operator&()
Big::operator&=()
Big::operator|()
Big::operator|=()
Big::operator^()
Big::operator^=()
for Big<> we do not define bitwise neg
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@302 e52654a7-88a9-db11-a3e9-0013d4bc506e
if defined then the library does not use wide characters
(wchar_t, std::wstring, ...) this is a workaround for some compilers
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@294 e52654a7-88a9-db11-a3e9-0013d4bc506e
this has impact on 64 bit platforms
fixed: some warnings from Visual C++ (64 bit)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@245 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed: added specializations to Big::ToString() when the base is equal 4, 8 or 16
the previous version was not accurate on some last digits (after the comma operator)
consider this binary value (32 bit mantissa):
base 2: 1.1111 1111 1111 1111 1111 1111 1110 101
previous ToString() gave:
base 4: 1.33333333333332
base 8: 1.777777777
base 16: 1.FFFFFF
now we have:
base 4: 1.3333333333333222
base 8: 1.77777777724
base 16: 1.FFFFFFEA
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@238 e52654a7-88a9-db11-a3e9-0013d4bc506e
UInt::Pow(UInt<value_size> pow)
Big::Pow(UInt<pow_size> pow)
Big::PowUInt(Big<exp, man> pow)
when 'pow' was sufficient large the algorithm returned carry
but the result could have been calculated correctly
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@213 e52654a7-88a9-db11-a3e9-0013d4bc506e
didn't want to compile
moved: UInt<>::SkipWhiteCharacters() to Misc::SkipWhiteCharacters()
UInt<>::CharToDigit() to Misc::CharToDigit()
UInt<>::DigitToChar() to Misc::DigitToChar()
removed: Parser::CharToDigit() - was duplicated (it's the same as Misc::CharToDigit())
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@198 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: wide characters can be used simultaneously with ascii characters
now we have two kind of methods: one for ascii characters and the other for wide characters
e.g.
void UInt::ToString(std::string & result)
void UInt::ToString(std::wstring & result)
previous was only one:
void UInt::ToString(tt_string & result)
and the 'tt_string' was a typedef to either std::string or std::wstring
and it was a little misleading to a user (he has to know what the tt_string is)
added: file: ttmathmisc.h some useful functions
changed: classes: ExceptionInfo, ReferenceError and RuntimeError are used only with ascii characters
removed: macros: TTMATH_USE_WCHAR, TTMATH_TEXT()
removed: typedefs: tt_char, tt_string, tt_ostringstream, tt_ostream, tt_istream
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@193 e52654a7-88a9-db11-a3e9-0013d4bc506e
wide characters are used when macro TTMATH_USE_WCHAR is defined
this macro is defined automatically when there is macro UNICODE or _UNICODE defined
some types have been changed
char -> tt_char
std::string -> tt_string
std::ostringstream -> tt_ostringstream
std::ostream -> tt_ostream
std::istream -> tt_istream
normally tt_char is equal char but when you are using wide characters then tt_char will be wchar_t (and so on)
(all typedef's are in ttmathtypes.h)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@177 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed: some cosmetic changes to get rid of warnings generated by
MS Visual 2008 when warning level is 4
changed: names of labels in asm code: p to ttmath_loop, end to ttmath_end
p2 to ttmath_loop2
Robert Muir reported that there was a confict with boost::end
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@156 e52654a7-88a9-db11-a3e9-0013d4bc506e
used for debugging purposes by macro TTMATH_LOG(msg)
(it is used in nearly all methods in UInt class)
added: macro TTMATH_DEBUG_LOG: when defined then TTMATH_LOG()
put some debug information (to std::cout)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@125 e52654a7-88a9-db11-a3e9-0013d4bc506e
(radix) -- operators '#' and '&', e.g.:
'#sin(1)' was equal '0' -- there was a zero from '#' and then
it was multipied by 'sin(1)'
the parser didn't check whether Big::FromString() has actually
read a proper value -- the method Big::FromString() didn't have
something to report such a situation
fixed: Big::FromString() when the base is 10, the method reads the scientific
part only if such a part it correctly supplied, e.g:
'1234e10', '1234e+10', '1234e-5'
previous '1234e' was treated as: '1234e0' (now parsing stops on 'e' and
the 'e' can be parsed by other parsers, e.g. the mathematical
parser -- now in the parser would be: '1234e' = '1234 * e' = '3354,3597...' )
added: to Int::FromString(): parameter 'const char ** after_source = 0'
if exists it's pointing at the end of the parsed string
added: to UInt::FromString(), Int::FromString(), Big::FromString():
parameter 'bool * value_read = 0' - (if exists) tells
whether something has actually been read (at least one digit)
added: the parser checks itself for the operators for changing the base
(operators '#' and '&')
changed: in the parser: the form with operators '#' and '&' is as follows:
[-|+][#|&]numeric_value
previous was: [-|+][#|&][-|+]numeric_value
removed: Big::FromString() this method doesn't longer recognize operators
for changing the base ('#' and '&')
changed: in the parser: the short form of multiplication has the same
priority as the normal multiplication, e.g.:
'2x^3' = 2 * (x^3)
previous the priority was greater than powering priority
previous: '2x^3' = (2*x) ^ 3
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@113 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed: the size of built-in variables (constants) in ttmathbig.h
now they consist of 256 32bit words
macro TTMATH_BUILTIN_VARIABLES_SIZE is equal: 256u on a 32bit platform and 128ul on a 64bit platform
added: macro CONSTANTSGENERATOR which is useful for generating constants
(it's used by 'gen' program in 'constgen' directory)
after declaring this macro the methods: ExpSurrounding0() and LnSurrounding1() will be public visible
and the inner loop can do more iterations than TTMATH_ARITHMETIC_MAX_LOOP
changed: in methods: ExpSurrounding0() and LnSurrounding1() - the way of comparising with the last word
(now we're comparing not with the last state but with a state from a few words back)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@105 e52654a7-88a9-db11-a3e9-0013d4bc506e
fixed: Big::Add incorrectly rounded 'this' when both exponents were equal
it caused that sometimes when adding a zero the result has changed
this had impact among other things on FromString() method
"0,8" had different binary representation from "0,80"
changed: renamed: Big::PowUInt(UInt<pow_size> pow) -> Big::Pow(UInt<pow_size> pow)
it returns 2 when there is: 0^0
changed: renamed: Big::PowInt(Int<pow_size> pow) -> Big::Pow(Int<pow_size> pow)
it returns 2 when there is: 0^0 or 0^(-something)
changed: renamed: Big::PowBUInt() -> PowUInt(), Big::PowBInt() -> Big::PowInt()
they return 2 when the arguments are incorrect (like above)
changed: UInt::SetBitInWord(uint & value, uint bit) is taking the first argument by a reference now,
the specific bit is set in the 'value' and the method returns the last state of the bit (zero or one)
added: UInt::GetBit(uint bit_index) - returning the state of the specific bit
changed: UInt::SetBit(uint bit_index) - it's using TTMATH_ASSERT now
changed: Big::Mod2() - it's using mantissa.GetBit() now
added: Big::operator=(double) and Big::Big(double)
added: TTMATH_ASSERT somewhere in ttmathuint64.h
added: UInt::Pow(UInt<value_size> pow) and Int::Pow(Int<value_size> pow)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@104 e52654a7-88a9-db11-a3e9-0013d4bc506e
RadToDeg(rad), Ceil(x), Floor(x), Sqrt(x), Sinh(x), Cosh(x),
Tanh(x) /Tgh(x)/, Coth(x) /Ctgh(x)/
changed: class Objects in ttmathobjects.h has been completely rewritten, we can
change the names of user-defined variables or functions, and the names are
case-sensitive now
added: class History which is used in functions which take a lot of time
during calculating e.g. Factorial(x)
added: Tg(x) a wrapper for Tan(x)
changed: CTan(x) is Cot(x) now
added: Ctg(x) a wrapper for Cot(x)
added: ATg(x) a wrapper for ATan(x)
changed: ACTan(x) is ACot(x) now
added: ACtg(x) a wrapper for ACot(x)
added: UInt::PrintTable() (for debugging etc.)
changed: the methods Big::SetPi() Big::SetE() and Big::SetLn2() have been
rewritten, now they have 128 32bit words (it's about 1232 valid
decimal digits)
fixed: previous values from Big::SetPi() Big::SetE() and Big::SetLn2() were
not too much accurate (last 2-3 words were wrong)
added: Big::SetLn10() (128 32bit words as well)
added: macro: TTMATH_BUILTIN_VARIABLES_SIZE which is equal 128u on 32bit
platforms and 64ul on 64bit platforms (128/2=64)
added: macros: TTMATH_PLATFORM32 and TTMATH_PLATFORM64
changed: a small optimisation in UInt::Mul2Big()
added: at the end of ttmath.h: #include "ttmathparser.h"
this is for convenience for a programmer, he can only use #include
with ttmath.h even if he uses the parser
added: to samples: big.cpp, parser.cpp
fixed: constructor Big::Big(uint) - it was wrong because
it was using the method Big::FromInt(sint) which could produce wrong
values (if the 'uint' couldn't correctly be casted into the 'sint')
added: Big::FromUInt(uint)
changed: Big::FromInt(sint), Big::SetOne(), renamed Big::SetDotOne() into
Big::Set05()
(they are a little faster now)
added: Big::operator=(uint)
changed: in 64bit mode: constructor: Big::Big(int)
added: in 64bit mode: constructor: Big::Big(unsigned int),
operators: Big::operator=(signed int) and Big::operator=(unsigned int)
(these operators and the constructor take a 32bit value)
deleted: the word 'virtual' from destructors: UInt, Int, Big
(types in this library are not projected to be base-classes for
another ones derived from them)
changed: UInt::operator=(uint), UInt::UInt(uint), Int::operator=(sint), Int::Int(sint)
added: UInt::FromUInt(uint), UInt::operator=(sint), UInt::UInt(sint),
Int::FromInt(sint), Int::operator=(uint), Int::Int(uint),
Int::operator==(const Int<>&), Int::operator!=(const Int<>&)
added: in 64bit mode: UInt::operator=(unsigned int), UInt::UInt(unsigned int),
UInt::operator=(signed int), UInt::UInt(signed int)
(these operators and the constructors take a 32bit value)
added: in 64bit mode: Int::operator=(signed int), Int::Int(signed int),
Int::operator=(unsigned int), Int::Int(unsigned int)
(these operators and the constructors take a 32bit value)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@25 e52654a7-88a9-db11-a3e9-0013d4bc506e
fixed: bad sizes in tables in some 'Set...' methods in the Big class
fixed: Big::FromInt(Int<int_size> value) - the sign must be set at the end because SetSign
checks whether there is zero and depends on it sets the sign or not
(this was the stupid error which causes sometimes the errors 'overflow during printing')
fixed: Big::SetMin - the sign must be set at the and
changed: Big::Pow can use the reference now (the problem was actually with the Big::FromInt)
added: a namespace 'auxiliaryfunctions' (in ttmath.h)
added: ATan - arc tan, ACTan - arc ctan
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@17 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed Int::Div -- a remainder is not returning now but taking as a parameter (a pointer or reference)
changed order in parameters in UInt::AddTwoInts
added Int::AddInt
added Int::AddTwoInts
added Int::SubInt
changed Int::AddOne and Int::SubOne (much faster now)
fixed a bug in UInt::operator--() and Int::operator--() (there was adding instead of subtracting)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@13 e52654a7-88a9-db11-a3e9-0013d4bc506e
added UInt::AddInt and UInt::SubInt
changed UInt::AddOne and UInt::SubOne (much faster now)
added UInt::SetBitInWord
changed UInt::SetBit (much faster now)
UInt::AddTwoUints renamed to UInt::AddTwoInts
UInt::FindLeadingBit32 renamed to UInt::FindLeadingBitInWord
added UInt::SetBitInWord
UInt::Mul64 renamed to UInt::MulTwoWords
UInt::Div64 renamed to UInt::DivTwoWords
and more small changes in UInt type
start adding support for Amd64 (not finished yet) (added ttmathuint64.h)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@12 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed kind of templates in ttmath.h (template<class ValueType> is now)
added TTMATH_RELEASE macro
added TTMATH_ prefix into macros
changed multiplication in UInt type (now we can use both algorithm in the same time)
added ExceptionInfo, ReferenceError and RuntimeError classes
now TTMATH_ASSERT throws another type of object
added TTMATH_REFERENCE_ASSERT (it is instead of MATHTT_THIS_ASSERT)
