if defined then the library does not use wide characters
(wchar_t, std::wstring, ...) this is a workaround for some compilers
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@294 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: wide characters can be used simultaneously with ascii characters
now we have two kind of methods: one for ascii characters and the other for wide characters
e.g.
void UInt::ToString(std::string & result)
void UInt::ToString(std::wstring & result)
previous was only one:
void UInt::ToString(tt_string & result)
and the 'tt_string' was a typedef to either std::string or std::wstring
and it was a little misleading to a user (he has to know what the tt_string is)
added: file: ttmathmisc.h some useful functions
changed: classes: ExceptionInfo, ReferenceError and RuntimeError are used only with ascii characters
removed: macros: TTMATH_USE_WCHAR, TTMATH_TEXT()
removed: typedefs: tt_char, tt_string, tt_ostringstream, tt_ostream, tt_istream
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@193 e52654a7-88a9-db11-a3e9-0013d4bc506e
you should compile with TTMATH_MULTITHREADS
and use TTMATH_MULTITHREADS_HELPER macro somewhere in your *.cpp file
added file: ttmaththreads.h (look there for more info)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@183 e52654a7-88a9-db11-a3e9-0013d4bc506e
* added: gamma() function to the parser
* added: Big::IsInteger() method
returns true if the value is integer
* added: CGamma<ValueType> class
is used with Gamma() and Factorial() in multithreaded environment
* changed: Factorial() is using the Gamma() function now
* 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

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)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@177 e52654a7-88a9-db11-a3e9-0013d4bc506e
e.g. '5y', (it's used only if the second parameter
is a variable or function)
changed: variables and functions are case-sensitive now
added: variables and functions can have underline characters
in their names
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@61 e52654a7-88a9-db11-a3e9-0013d4bc506e
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)

(user-defined variables/functions in the mathematical parser)
added: into the parser: logical operators: > < >= <= == != && ||
added: into the parser: logical functions: and() or() not() if()
changed: a method for looking for a mathematical operator
(there's the operators table now)
added: ErrorCode::err_unknown_operator when the parser couldn't read an operator
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@23 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed kind of templates in ttmath.h (template<class ValueType> is now)
added TTMATH_RELEASE macro
added TTMATH_ prefix into macros
changed multiplication in UInt type (now we can use both algorithm in the same time)
added ExceptionInfo, ReferenceError and RuntimeError classes
now TTMATH_ASSERT throws another type of object
added TTMATH_REFERENCE_ASSERT (it is instead of MATHTT_THIS_ASSERT)
