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.

be8913866a - 32 bit ASM code and ASSERTS did not work as the ASM code put its result in EAX, but the ASSERT afterwards did destroy the EAX's contents, of course.

d7b67e4d47 - minor changes for ASSERT macros

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)
@@ -7,117 +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)

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.
