5597373093 - "streamlined" ttmathconfig.h a bit:
a) Unicode support if TTMATH_USE_WCHAR is set (compiler must know wchar_t etc, of course)
  b) threading synchonisation uses WIN32 instead of __MSVC__ define, as this is OS dependent, not compiler dependent

de58378488 - added AboutEqualWithoutSign() to big<> to allow 'suppression' of some unexpected results (that are perfectly logical though, given the possibly unrepresentable nature of binary representation of decimals) like
big<>("10.456466") * 2 == big<>("20.912932")

resulting in FALSE result.

d7b67e4d47 - minor changes for ASSERT macros

@@ -1,119 +1,15 @@
Version 0.9.2 (2010.09.23):
* fixed: Big::Add() sometimes incorrectly rounded the last bit from its mantissa
* fixed: Big::BigAnd() Big::BigOr() Big::BigXor() should have set NaN
when the argument was negative (they only returned 2)
* fixed: recurrence calling in Big::FromString(const std::string &, uint, const wchar_t **, bool *)
it should have the signature: Big::FromString(const std::string &, uint, const char **, bool *)
* fixed: Big::ToString method
in some cases when in the output string the exponent should be equal zero
the method changes the exponent to one so the last digit from the mantissa
was lost
* fixed: Big::ToDouble(double &) set always +INF (infinity)
when the value was too large (even for negative values)
(it should set -INF in such a case)
* 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
Big::operator++()
Big::operator++(int)
Big::operator--()
Big::operator--(int)
* added: macro TTMATH_DONT_USE_WCHAR
if defined then the library does not use wide characters
(wchar_t, std::wstring, ...) this is a workaround for some compilers
* added: bool UInt::IsOnlyTheHighestBitSet()
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
* added: macro TTMATH_BIG_DEFAULT_CLEAR
when defined the default constructor from Big<> clears its mantissa and exponent
Big<1, 2> var;
var.mantissa and var.exponent will be set to zero
(but var has the NaN flag set too - it is not zero value, this is mainly for debug purposes)
* added: only on 32bit platforms:
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
* 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
* added: double Big::ToDouble() /there was only Big::ToDouble(double &) /
uint Big::ToFloat(float &)
float Big::ToFloat()
* changed: now asm version is available only on x86 and amd64
(and only for GCC and MS VC compilers)
* removed: macro TTMATH_RELEASE (now the 'release' version is default)
for debug version define TTMATH_DEBUG macro
TTMATH_DEBUG is also automatically defined when DEBUG or _DEBUG is set
* removed: macro TTMATH_REFERENCE_ASSERT from all methods in public interface
Version 0.9.1 (2010.02.07):
* fixed: the parser didn't use characters for changing the base (# and &)
those characters were skipped
(this bug was introduced in 0.9.0)
* fixed: added in the parser: operator's associativity
operator ^ (powering) is right-associative:
sample: 2^3^4 is equal 2^(3^4) and it is: 2.41e+24
previously was: 2^3^4 = (2^3)^4 = 4096
* fixed: in Big::ToString_CreateNewMantissaAndExponent() changed the formula:
new_exp_ = [log base (2^exponent)] + 1
now the part '+ 1' is only made when the logarithm is positive and with fraction
if the value is negative we can only skip the fraction, previously
we lost some last digits from the new mantissa
Consider this binary value (32 bit mantissa):
(bin)1.0000000000000000000000000000011
previously ToString() gave 1, now we have: 1.000000001
* changed: in Big::ToString() the base rounding is made only if the result value
would not be an integer, e.g. if the value is 1.999999999999 then
the base rounding will not be done - because as the result would be 2
* added: IEEE 754 half-to-even rounding (bankers' rounding) to the following
floating point algorithms: Big::Add, Big::Sub, Big::Mul, Big::Div
* added: static sint UInt<value_size>::FindLowestBitInWord(uint x)
this method is looking for the lowest set bit in a word
* added: UInt::FindLowestBit(uint & table_id, uint & index)
this method is looking for the lowest set bit
Version 0.9.0 (2009.11.25):
* added: support for wide characters (wchar_t, std::wstring)
Version 0.9.0 prerelease (2009.07.16):
* added: support for wide characters (wchar_t)
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)
* added: Big::IsInteger()
returns true if the value is integer (without fraction)
(NaN flag is not checked)
@@ -121,117 +17,10 @@ Version 0.9.0 (2009.11.25):
* added: gamma() function to the parser
* added: CGamma<ValueType> class
is used with Gamma() and Factorial() in multithreaded environment
* added: multithread support for Big<> class
you should compile with TTMATH_MULTITHREADS
and use TTMATH_MULTITHREADS_HELPER macro somewhere in your *.cpp file
* added: x86_64 asm code for Microsoft Visual compiler
file: ttmathuint_x86_64_msvc.asm
(this file should be compiled first because MS VC doesn't support inline assembler in x86_64 mode)
* added: flag TTMATH_BIG_ZERO to Big<> class
if this flag is set then there is a value zero
Big::IsZero() is faster now
* added: Big::ClearInfoBit(unsigned char)
Big::SetInfoBit(unsigned char)
Big::IsInfoBit(unsigned char)
some methods for manipulating the info flags
* added: macro: TTMATH_BITS(min_bits)
which returns the number of machine words
capable to hold min_bits bits
* added: bool Parser::Calculated()
this method returns true is something was calculated
(at least one mathematical operator was used or a function or variable)
* added: to the parser: operator percentage
e.g. 1000-50%=1000-(1000*0,5)=500
* added: struct: Conv
consists of some parameters used
in ToString() and FromString()
* added: Big::ToString() can group digits
e.g. 1234567 -> 1`234`567
* added: Parser::SetGroup(int g)
Parser::SetComma(int c, int c2 = 0)
Parser::SetParamSep(int s)
* added: std::string UInt::ToString(uint b = 10)
std::wstring UInt::ToWString(uint b = 10)
std::string Int::ToString(uint b = 10)
std::wstring Int::ToWString(uint b = 10)

std::string Big::ToString(const Conv & conv)
std::string Big::ToString()
std::wstring Big::ToWString(const Conv & conv)

* added: uint FromString(const char * source, const Conv & conv, const char **, bool *)
uint FromString(const wchar_t * source, const Conv & conv, const wchar_t **, bool *)
uint FromString(const std::string & string, const Conv & conv, const wchar_t **, bool *)
uint FromString(const std::wstring & string, const Conv & conv, const wchar_t **, bool *)
* added: UInt::Sqrt() - a new algorithm for calculating the square root
* added: to the parser: function frac() - returns a value without the integer part
(only fraction remains)
* added: Int::DivInt(sint divisor, sint * remainder)
* added: const char * UInt::LibTypeStr()
const char * Big::LibTypeStr()
LibTypeCode UInt::LibType()
LibTypeCode Big::LibType()
returning a string/enum represents the currect type of the library
we have following types:
asm_vc_32 - with asm code designed for Microsoft Visual C++ (32 bits)
asm_gcc_32 - with asm code designed for GCC (32 bits)
asm_vc_64 - with asm for VC (64 bit)
asm_gcc_64 - with asm for GCC (64 bit)
no_asm_32 - pure C++ version (32 bit) - without any asm code
no_asm_64 - pure C++ version (64 bit) - without any asm code
* added: UInt::operator>>(int)
UInt::operator>>=(int)
UInt::operator<<(int)
UInt::operator<<=(int)
* changed: Factorial() is using the Gamma() function now
* changed: Big::Div(ss2)
Big::Mod(ss2)
they return 2 when ss2 is zero
previously returned 1
* changed: algorithms in Big::Sqrt() and ttmath::Root(x ; n)
they were not too much accurate for some integers
e.g. Root(16;4) returned a value very closed to 2 (not exactly 2)
* 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
* changed: in Big::ToString() some additional rounding (base_round) is now made only
when the value is not an integer
* changed: another compilers than MS VC or GCC by default use no asm version (TTMATH_NOASM)
* removed: Parser<>::SetFactorialMax() method
the factorial() is such a fast now that we don't need the method longer
* removed: ErrorCode::err_too_big_factorial
* removed: macros: TTMATH_COMMA_CHARACTER_1 and TTMATH_COMMA_CHARACTER_2
the comma characters we have in Conv struct now
Version 0.8.6 (2009.10.25):
* 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')
* fixed: buffer overflow in Big::ToInt(Int<int_size> & result)
* fixed: powering algorithm in:
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

TTMath is developed under the BSD licence which means that it is free
for both personal and commercial use.
The library has some technical limitations:
* there are only two platforms that are supported: x86 and x86_64,
* you can use this library only with the C++ programming language.
The main goal of the library is to allow one to use big values in the same
way as the standard types like int or float. It does not need to be compiled
first because the whole library is written as the C++ templates. This means
only C++ developers can use this library and one thing they have to do is
to use 'include' directive of the preprocessor. How big the values can be
is set at compile time.
