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)

TTMath - a bignum library for C++ TTMath is a small library which allows one to perform arithmetic operations with big unsigned integer, big signed integer and big floating point numbers. It provides standard mathematical operations like adding, subtracting, multiplying, dividing etc. With the library also goes a mathematical parser which helps you solving input formulas read directly from a user. TTMath is developed under the (new) BSD licence which means that it is free for both personal and commercial use but the library has some technical limitations: you can use it only on i386 and Amd64, another platforms are not supported (Intel 64bit platforms were not tested but should work as well), and 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, float, etc. 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 directly in the source code by the programmer. Author: Tomasz Sowa <t.sowa AnTispam slimaczek.pl> Home page: http://sourceforge.net/projects/ttmath
