Tomasz Sowa a40e951923 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 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
       *** version for 64 bit platforms are not tested yet ***
added: double Big::ToDouble() /there was only Big::ToDouble(double &) /
       uint Big::ToFloat(float &)
       float Big::ToFloat()

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.
