Version 0.8.0 (2007.03.28):
|
|
* added: into the parser: SetFactorialMax()
|
|
* added: DegToDeg(deg, min, sec), DegToRad(deg), DegToRad(deg, min, sec),
|
|
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
|
|
* added/changes/fixed: in copy-constructors and operators= in Int,
|
|
Uint and Big (more info in the commit log)
|
|
* renamed Big::SetDotOne() into Big::Set05()
|
|
* changes: a few small optimisations in Big
|
|
* 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)
|
|
* and more small changes (look at the commit log)
|
|
|
|
Version 0.7.2 (2007.03.09):
|
|
* added: Big::Mod - the remainder from a division
|
|
* added: Big::Sgn - the 'sign' from the value (-1,0,1)
|
|
* added: global functions Mod and Sgn too
|
|
* added: checking whether a user gives a correct value of a variable or function
|
|
(user-defined variables/functions in the mathematical parser)
|
|
* added: into the parser: logical operators: > < >= <= == != && ||
|
|
* added: into the parser: logical functions: and() or() not() if()
|
|
* added: ErrorCode::err_unknown_operator when the parser couldn't read an operator
|
|
|
|
Version 0.7.1 (2007.02.27):
|
|
* fixed the error 'overflow during printing' which was caused
|
|
by Big::FromInt(Int<int_size> value) (the sign has to be set at the end)
|
|
* fixed many small errors
|
|
* added ATan (arctan), ACTan (arc ctan) functions
|
|
|
|
Version 0.7.0 (2007.02.24):
|
|
* finished support for 64bit platforms
|
|
* added ASin (arcsin), ACos (arccos) functions
|
|
|
|
Version 0.6.4 (2007.01.29):
|
|
* fixed the problem with a sign in the mathematical parser /-(1) was 1/
|
|
* 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)
|
|
|
|
Version 0.6.3 (2007.01.22):
|
|
* position of arguments (x and base) in logarithm functions are swapped
|
|
* it's possible to use any multiplication algorithms in the same time
|
|
(macros UINT_MUL_VERSION_'X' have gone)
|
|
* added ExceptionInfo, ReferenceError and RuntimeError classes
|
|
* the mess in macros has been cleaned up
|
|
* added TTMATH_RELEASE macro
|
|
|
|
Version 0.6.2 (2007.01.10):
|
|
* New division algorithm (radix b) where b is 2^32
