-Version 0.9.2 (2010.09.23):
+Version 0.9.0 prerelease (2009.07.16):
-    * fixed:   Big::Add() sometimes incorrectly rounded the last bit from its mantissa
+    * added:   support for wide characters (wchar_t)
-    * fixed:   Big::BigAnd() Big::BigOr() Big::BigXor() should have set NaN
+               wide characters are used when macro TTMATH_USE_WCHAR is defined
-               when the argument was negative (they only returned 2)
+               this macro is defined automatically when there is macro UNICODE or _UNICODE defined
-    * fixed:   recurrence calling in Big::FromString(const std::string &, uint, const wchar_t **, bool *)
+               some types have been changed
-               it should have the signature: Big::FromString(const std::string &, uint, const char **, bool *)               
+                 char               -> tt_char
-    * fixed:   Big::ToString method
+                 std::string        -> tt_string
-               in some cases when in the output string the exponent should be equal zero
+                 std::ostringstream -> tt_ostringstream
-               the method changes the exponent to one so the last digit from the mantissa
+                 std::ostream       -> tt_ostream
-               was lost
+                 std::istream       -> tt_istream
-    * fixed:   Big::ToDouble(double &) set always +INF (infinity)
+               normally tt_char is equal char but when you are using wide characters then tt_char will be wchar_t (and so on)
-               when the value was too large (even for negative values)
+               (all typedef's are in ttmathtypes.h)
-               (it should set -INF in such a case)
-    * added:   some missing operators
-               UInt::operator~()    /* bitwise neg  */
-               UInt::operator&()    /* bitwise and  */
-               UInt::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 &)

-               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
-               (this bug was introduced in 0.9.0)
-    * fixed:   added in the parser: operator's associativity
-               operator ^ (powering) is right-associative:
-               sample: 2^3^4 is equal 2^(3^4) and it is: 2.41e+24
-               previously was: 2^3^4 = (2^3)^4 = 4096
-    * fixed:   in Big::ToString_CreateNewMantissaAndExponent() changed the formula:
-               new_exp_ = [log base (2^exponent)] + 1
-               now the part '+ 1' is only made when the logarithm is positive and with fraction
-               if the value is negative we can only skip the fraction, previously
-               we lost some last digits from the new mantissa
-               Consider this binary value (32 bit mantissa):
-               (bin)1.0000000000000000000000000000011
-               previously ToString() gave 1, now we have: 1.000000001
-    * changed: in Big::ToString() the base rounding is made only if the result value
-               would not be an integer, e.g. if the value is 1.999999999999 then
-               the base rounding will not be done - because as the result would be 2
-    * added:   IEEE 754 half-to-even rounding (bankers' rounding) to the following
-               floating point algorithms: Big::Add, Big::Sub, Big::Mul, Big::Div
-    * added:   static sint UInt<value_size>::FindLowestBitInWord(uint x)
-               this method is looking for the lowest set bit in a word
-    * added:   UInt::FindLowestBit(uint & table_id, uint & index)
-               this method is looking for the lowest set bit
-
-               
-Version 0.9.0 (2009.11.25):
-    * added:   support for wide characters (wchar_t, std::wstring)
     * added:   Big::IsInteger()
                returns true if the value is integer (without fraction)
                (NaN flag is not checked)

-    * added:   multithread support for Big<> class

-    * changed: added specializations to Big::ToString() when the base is equal 4, 8 or 16
-               the previous version was not accurate on some last digits (after the comma operator)

-                  base 16: 1.FFFFFFEA
-    * changed: in Big::ToString() some additional rounding (base_round) is now made only 
-               when the value is not an integer
-    * changed: another compilers than MS VC or GCC by default use no asm version (TTMATH_NOASM)
     * 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
-    * removed: macros: TTMATH_COMMA_CHARACTER_1 and TTMATH_COMMA_CHARACTER_2

-    * fixed:   UInt::SetBitInWord(uint & value, uint bit) set 1 if the bit was
-               equal 1 (should be set 2)
-               this affected only no-asm parts - when macro TTMATH_NOASM was defined
-    * fixed:   UInt<value_size>::MulInt(uint ss2)
-               there was a buffer overflow when value_size was equal 1
-    * fixed:   UInt::AddVector() and UInt::SubVector() didn't want to compile
-               when macro TTMATH_NOASM was defined
-    * fixed:   Big::operator>> didn't correctly recognize values in scientific mode (with 'e' character)
-    * fixed:   Int::FromString(const tt_string & s, uint b = 10)
-               didn't use 'b' (always was '10')
-    * fixed:   buffer overflow in Big::ToInt(Int<int_size> & result)
-    * fixed:   powering algorithm in:
-               UInt::Pow(UInt<value_size> pow)
-               Big::Pow(UInt<pow_size> pow)
-               Big::PowUInt(Big<exp, man> pow)
-               when 'pow' was sufficient large the algorithm returned carry
-               but the result could have been calculated correctly
