added: DegToDeg(deg, min, sec), DegToRad(deg), DegToRad(deg, min, sec),

Browse Source 
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)
