Version 0.8.3 prerelease (2009.03.24):
* fixed: RclMoveAllWords() and RcrMoveAllWords() sometimes didn't return
the proper carry, (when 'bits' was greater than or equal to 'value_size')
this had impact on Rcl() and Rcr(), they also returned the wrong carry
* fixed: UInt::Div() didn't return a correct result when the divisor was equal 1
there was an error in UInt::DivInt() - when the divisor was 1 it returned
zero and the carry was set
* fixed: there was a TTMATH_REREFENCE_ASSERT error in Big::PowUInt() caused by: start.Mul(start)
* fixed: Big::Add incorrectly rounded 'this' when both exponents were equal
it caused that sometimes when adding a zero the result has changed
this had impact among other things on FromString() method
"0,8" had different binary representation from "0,80"
* fixed: template Big::FromBig(const Big<another_exp, another_man> & another)
didn't correctly set the exponent (when the mantisses had different size -
when 'man' was different from 'another_man')
this had impact on operator= too
sample:
Big<2,3> a = 100;
Big<3,5> b;
b = a; // b had a wrong value
* changed: UInt::FromString, added a parametr 'after_source'
which is pointing at the end of the parsing string
* changed: renamed: Big::PowUInt(UInt<pow_size> pow) -> Big::Pow(UInt<pow_size> pow)
it returns 2 when there is: 0^0
* changed: renamed: Big::PowInt(Int<pow_size> pow) -> Big::Pow(Int<pow_size> pow)
it returns 2 when there is: 0^0 or 0^(-something)
* changed: renamed: Big::PowBUInt() -> PowUInt(), Big::PowBInt() -> Big::PowInt()
they return 2 when the arguments are incorrect (like above)
* changed: UInt::SetBitInWord(uint & value, uint bit) is taking the first argument by a reference now,
the specific bit is set in the 'value' and the method returns the last state of the bit (zero or one)
* changed: UInt::SetBit(uint bit_index) - it's using TTMATH_ASSERT now
* changed: the size of built-in variables (constants) in ttmathbig.h
now they consist of 256 32bit words
macro TTMATH_BUILTIN_VARIABLES_SIZE is equal: 256u on a 32bit platform and 128ul on a 64bit platform
* changed: the asm code in ttmathuint.h and ttmathuint64.h has been completely rewritten (much faster now)
* added: UInt::GetBit(uint bit_index) - returning the state of the specific bit
* added: Big::operator=(double) and Big::Big(double)
* added: UInt::Pow(UInt<value_size> pow) and Int::Pow(Int<value_size> pow)
Version 0.8.2 (2008.06.18):
* added: UInt::BitNot2() this method has been proposed by
Arek <kmicicc AnTispam users.sourceforge.net>
