2.10 Numerical Limits

The two standard include files, LIMITS.H and FLOAT.H, define the “numerical limits,” or minimum and maximum values, a variable of a given type can hold. These minimums and maximums are guaranteed to be portable to any C++ compiler that uses the same data representation as ANSI C. The LIMITS.H include file defines the numerical limits for integral types, and FLOAT.H defines the numeric limits for floating types.
