CHANGELOG

@@ -1,3 +1,90 @@
+Version 0.9.2 (2010.09.23):
+    * 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 *)               
+    * fixed:   Big::ToString method
+               in some cases when in the output string the exponent should be equal zero
+               the method changes the exponent to one so the last digit from the mantissa
+               was lost
+    * fixed:   Big::ToDouble(double &) set always +INF (infinity)
+               when the value was too large (even for negative values)
+               (it should set -INF in such a case)
+    * 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
+               Big::operator++()
+               Big::operator++(int)
+               Big::operator--()
+               Big::operator--(int)
+    * 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
+    * added:   macro TTMATH_BIG_DEFAULT_CLEAR
+               when defined the default constructor from Big<> clears its mantissa and exponent
+               Big<1, 2> var;
+               var.mantissa and var.exponent will be set to zero
+               (but var has the NaN flag set too - it is not zero value, this is mainly for debug purposes)
+    * added:   only on 32bit platforms:
+               uint UInt::FromUInt(uint64_t n)
+               uint Int::FromInt(int64_t n)
+               void Big::FromUInt(uint64_t n)
+               void Big::FromInt(int64_t n)        
+               and appropriate constructors and operators
+    * added:   TTMATH_FORCEASM macro
+               asm version of the library is available by default only for:
+               x86 and amd64 platforms and for Microsoft Visual and GCC compilers,
+               but you can force using asm version (the same asm as for Microsoft Visual)
+               by defining TTMATH_FORCEASM macro
+               you have to be sure that your compiler accept such an asm format
+    * added:   some missing methods for converting
+               for UInt<>, Int<> and Big<> classes:
+               uint ToUInt()
+               sint ToInt()
+               ToUInt(uint32_t &)
+               ToInt(uint32_t &)
+               ToInt(int32_t &)
+               ToUInt(uint64_t &)
+               ToInt(uint64_t &)
+               ToInt(int64_t &)
+               FromUInt(uint32_t &)
+               FromInt(uint32_t &)
+               FromInt(int32_t &)
+               FromUInt(uint64_t &)
+               FromInt(uint64_t &)
+               FromInt(int64_t &)
+               and appropriate constructors and operators
+    * added:   double Big::ToDouble() /there was only Big::ToDouble(double &) /
+               uint Big::ToFloat(float &)
+               float Big::ToFloat()
+    * changed: now asm version is available only on x86 and amd64
+               (and only for GCC and MS VC compilers)
+    * removed: macro TTMATH_RELEASE (now the 'release' version is default)
+               for debug version define TTMATH_DEBUG macro
+               TTMATH_DEBUG is also automatically defined when DEBUG or _DEBUG is set
+    * removed: macro TTMATH_REFERENCE_ASSERT from all methods in public interface
+
+
 Version 0.9.1 (2010.02.07):
     * fixed:   the parser didn't use characters for changing the base (# and &)
                those characters were skipped
