added: bool UInt::IsOnlyTheHighestBitSet()

Browse Source 
bool UInt::IsOnlyTheLowestBitSet()
         returning true if only the highest/lowest bit is set
added:   uint Int::MulInt(sint ss2)       
added:   void UInt::Swap(UInt<value_size> & ss2)       
         void Big::Swap(UInt<value_size> & ss2)
         method for swapping this for an argument
changed: small optimization in Big::Sub()
changed: now asm version is available only on x86 and amd64
         (and only for GCC and MS VC compilers)
removed: macro TTMATH_RELEASE
         for debug version define TTMATH_DEBUG macro
         TTMATH_DEBUG is also automatically defined when DEBUG or _DEBUG is set

Version 0.9.2 prerelease (2009.03.01):
Version 0.9.2 prerelease (2010.09.05):
* fixed: Big::Add() sometimes incorrectly rounded the last bit from its mantissa
* fixed: Big::BigAnd() Big::BigOr() Big::BigXor() should have set NaN
when the argument was negative (they only returned 2)
* fixed: recurrence calling in Big::FromString(const std::string &, uint, const wchar_t **, bool *)
it should have the signature: Big::FromString(const std::string &, uint, const char **, bool *)
* added: some missing operators
UInt::operator~() /* bitwise neg */
UInt::operator&() /* bitwise and */
UInt::operator&=()
UInt::operator|() /* bitwise or */
UInt::operator|=()
UInt::operator^() /* bitwise xor */
UInt::operator^=()
Big::operator&()
Big::operator&=()
Big::operator|()
Big::operator|=()
Big::operator^()
Big::operator^=()
for Big<> we do not define bitwise neg
* added: macro TTMATH_DONT_USE_WCHAR
if defined then the library does not use wide characters
(wchar_t, std::wstring, ...) this is a workaround for some compilers
* added: bool UInt::IsOnlyTheHighestBitSet()
bool UInt::IsOnlyTheLowestBitSet()
returning true if only the highest/lowest bit is set
* added: uint Int::MulInt(sint ss2)
* added: void UInt::Swap(UInt<value_size> & ss2)
void Big::Swap(UInt<value_size> & ss2)
method for swapping this for an argument
* changed: now asm version is available only on x86 and amd64
(and only for GCC and MS VC compilers)
* removed: macro TTMATH_RELEASE
for debug version define TTMATH_DEBUG macro
TTMATH_DEBUG is also automatically defined when DEBUG or _DEBUG is set
Version 0.9.1 (2010.02.07):
