fixed: UInt::SetBitInWord(uint & value, uint bit) set 1 if the bit was
equal 1 (should be set 2)
this affected only no-asm parts - when macro TTMATH_NOASM was defined
fixed: UInt<value_size>::MulInt(uint ss2)
there was a buffer overflow when value_size was equal 1
fixed: UInt::AddVector() and UInt::SubVector() didn't want to compile
when macro TTMATH_NOASM was defined
fixed: Big::operator>> didn't correctly recognize values in scientific mode (with 'e' character)
fixed: Int::FromString(const tt_string & s, uint b = 10)
didn't use 'b' (always was '10')
git-svn-id: svn://ttmath.org/publicrep/ttmath/branches/0.8.x@204 e52654a7-88a9-db11-a3e9-0013d4bc506e
fixed: some methods should set 'err_improper_argument' when the argument is a NaN object
(was: err_overflow)
changed: version of the library: 0.8.5 now
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@163 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

void UInt::Mul3Big(const UInt<value_size> & ss2, UInt<value_size*2> & result)
a new multiplication algorithm: Karatsuba multiplication,
on a vector UInt<100> with all items different from zero this algorithm is faster
about 3 times than Mul2Big(), and on a vector UInt<1000> with all items different from
zero this algorithm is faster more than 5 times than Mul2Big()
(measured on 32bit platform with GCC 4.3.3 with -O3 and -DTTMATH_RELEASE)
added: uint MulFastest(const UInt<value_size> & ss2)
void MulFastestBig(const UInt<value_size> & ss2, UInt<value_size*2> & result)
those methods are trying to select the fastest multiplication algorithm
changed: uint Mul(const UInt<value_size> & ss2, uint algorithm = 100)
void MulBig(const UInt<value_size> & ss2, UInt<value_size*2> & result, uint algorithm = 100)
those methods by default use MulFastest() and MulFastestBig()
changed: changed a little Mul2Big() to cooperate with Mul3Big()
changed: names of methods in macros TTMATH_LOG()
added: uint AddVector(const uint * ss1, const uint * ss2, uint ss1_size, uint ss2_size, uint * result)
uint SubVector(const uint * ss1, const uint * ss2, uint ss1_size, uint ss2_size, uint * result)
three forms: asm x86, asm x86_64, no-asm
those methods are used by the Karatsuba multiplication algorithm
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@148 e52654a7-88a9-db11-a3e9-0013d4bc506e
and the result was sometimes very big (even greater than x)
fixed: global function Mod(x) didn't set an ErrorCode object
fixed: global function Round() didn't test a carry
now it sets ErrorCode object
changed: function Sin(x) to Sin(x, ErrorCode * err=0)
when x was very big the function returns zero
now it sets ErrorCode object to err_overflow
and the result is undefined
the same is to Cos() function
changed: PrepareSin(x) is using Big::Mod() now when reducing 2PI period
should be a little accurate especially on a very big 'x'
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@143 e52654a7-88a9-db11-a3e9-0013d4bc506e
'typedef unsigned long long int ulint' has been put inside '#ifdef TTMATH_NOASM'
in order to not confuse a compiler while compiling with strict iso c++
(errors about not defining 'long long' in the c++ standard)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@137 e52654a7-88a9-db11-a3e9-0013d4bc506e
all the methods which are using assembler code have been
rewritten to no-asm forms, now we have:
1. asm for x86 file: ttmathuint_x86.h
2. asm for x86_64 file: ttmathuint_x86_64.h
3. no asm file: ttmathuint_noasm.h
(it's used when macro TTMATH_NOASM is defined)
The third form can be used on x86 and x86_64 as well and
on other platforms with a little effort.
(Temporarily I left there some '#ifdef's for debugging.)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@126 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
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
e.g. '5y', (it's used only if the second parameter
is a variable or function)
changed: variables and functions are case-sensitive now
added: variables and functions can have underline characters
in their names
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@61 e52654a7-88a9-db11-a3e9-0013d4bc506e
(when 'this' was negative)
added: Root(x; index) (and to the parser as well)
added: macro: TTMATH_PRERELEASE_VER (can be either zero or one)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@32 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
(user-defined variables/functions in the mathematical parser)
added: into the parser: logical operators: > < >= <= == != && ||
added: into the parser: logical functions: and() or() not() if()
changed: a method for looking for a mathematical operator
(there's the operators table now)
added: ErrorCode::err_unknown_operator when the parser couldn't read an operator
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@23 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
added: UInt::SetFromTable for 64bit code (now the support for 64bit
platforms seems to be completed)
added: asin - arc sin, acos - arc cos
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@16 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)
