Derived Floating Point Type Classes

The various floating point type classes differ only in their bounds. Consequently, a template is used to build up the required type classes automatically: 

template<class R> class float_type : public float_base {
   ... 
};
R denotes the corresponding floating point type info class. Note, only static methods defined in the class are executed here.
