Tomasz Sowa 39db6fc469 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

A bignum library for C++

TTMath is a small library which allows one to perform arithmetic operations
with big unsigned integer, big signed integer and big floating point numbers.
It provides standard mathematical operations like adding, subtracting,
multiplying, dividing. With the library also goes a mathematical parser to
help you solving mathematical expressions.

TTMath is developed under the BSD licence which means that it is free for
both personal and commercial use.

The main goal of the library is to allow one to use big values in the same
way as the standard types like int or float. It does not need to be compiled
first because the whole library is written as the C++ templates. This means
only C++ developers can use this library and one thing they have to do is
to use 'include' directive of the preprocessor. How big the values can be
is set at compile time.
