Tomasz Sowa 1e268f1808 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
 
       sample:
       Big<1,1> a;
       a.info = 0;
       a.mantissa = 2147483649u; // (bin) 10000000000000000000000000000001
       // first and last bit in the mantissa is set
       a.exponent = 0;
       std::cout << a << std::endl;

       priovious result: 2147483640
       it was treated as 214748364e+1

       also the method has been a little improved

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.
