the method do not check whether there is a zero or not now
(even if there's a zero the method can set a sign bit)
I changed this due to some prior errors
(errors corrected in revision 17, 49 and 58)
added: in Big::MulInt() checking whether the values are zeros
and if so the metdhod returns zero immediately
removed: file TODO (I didn't use it)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@66 e52654a7-88a9-db11-a3e9-0013d4bc506e
remove the -2 state
added: 'remove_trailing_zeroes' in Big::ToString()
it's either true or false
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@63 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
for converting from another kind of a Big class
added: to the parser: avg(), sum()
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@56 e52654a7-88a9-db11-a3e9-0013d4bc506e
there was SetSign() used when the value was not
defined, and also was a small mistake when the mantissa
was equal one word (on 32bit platforms)
added: uint Big::ToDouble(double&) - converting into double
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@49 e52654a7-88a9-db11-a3e9-0013d4bc506e
Big::ChangeSign()
added: ASinh(), ACosh(), ATanh() /ATgh()/, ACoth() /ACtgh()/
and to the parser as well
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@35 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed: UInt::Rcl(uint c=0) and UInt::Rcr(uint c=0) into
UInt::Rcl2(uint bits, uint c) and UInt::Rcr2(uint bits, uint c)
now they can move more than one bit and they are only private
fixed: UInt::Rcl(uint bits, uint c) and UInt::Rcr(uint bits, uint c)
didn't correctly return a carry if the 'bits' were equal
to 'value_size*TTMATH_BITS_PER_UINT'
changed: UInt::Rcl(uint bits, uint c) and UInt::Rcr(uint bits, uint c)
into UInt::Rcl(uint bits, uint c=0) and
UInt::Rcr(uint bits, uint c=0)
they are faster now when the bits is greater than a half of
the TTMATH_BITS_PER_UINT
changed: UInt::CompensationToLeft() it's faster now
changed: more small changes where there were UInt::Rcl(uint c=0) and
UInt::Rcr(uint c=0) used
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@34 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: Big::MulUInt(uint)
changed: Big::MulInt(sint)
added: Big::ToUInt(uint &)
changed: Big::ToInt(sint&)
changed: Factorial() it uses Big::MulUInt() at the beginning
(faster now especially more on a 32bit platform)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@33 e52654a7-88a9-db11-a3e9-0013d4bc506e
(when 'this' was negative)
added: Root(x; index) (and to the parser as well)
added: macro: TTMATH_PRERELEASE_VER (can be either zero or one)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@32 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)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@25 e52654a7-88a9-db11-a3e9-0013d4bc506e
(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
added: Big::Sgn - the 'sign' from the value (-1,0,1)
added: global functions Mod and Sgn too
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@19 e52654a7-88a9-db11-a3e9-0013d4bc506e
fixed: bad sizes in tables in some 'Set...' methods in the Big class
fixed: Big::FromInt(Int<int_size> value) - the sign must be set at the end because SetSign
checks whether there is zero and depends on it sets the sign or not
(this was the stupid error which causes sometimes the errors 'overflow during printing')
fixed: Big::SetMin - the sign must be set at the and
changed: Big::Pow can use the reference now (the problem was actually with the Big::FromInt)
added: a namespace 'auxiliaryfunctions' (in ttmath.h)
added: ATan - arc tan, ACTan - arc ctan
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@17 e52654a7-88a9-db11-a3e9-0013d4bc506e
added: UInt::SetFromTable for 64bit code (now the support for 64bit
platforms seems to be completed)
added: asin - arc sin, acos - arc cos
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@16 e52654a7-88a9-db11-a3e9-0013d4bc506e
changed Int::Div -- a remainder is not returning now but taking as a parameter (a pointer or reference)
changed order in parameters in UInt::AddTwoInts
added Int::AddInt
added Int::AddTwoInts
added Int::SubInt
changed Int::AddOne and Int::SubOne (much faster now)
fixed a bug in UInt::operator--() and Int::operator--() (there was adding instead of subtracting)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@13 e52654a7-88a9-db11-a3e9-0013d4bc506e
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)
git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@12 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)
