The two standard include files, <limits.h> and <float.h>, define the numerical limits, or minimum and maximum values that 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 numerical limits for floating types.
