<climits>

The <climits> header (from the C standard <limits.h> header) defines parameters that characterize integral types in the same way <cfloat> does for the floating point types. The native C++ header, <limits>, defines the same information (and more) using templates instead of macros.

The types used in the descriptions of the _MIN and _MAX macros are meant as reminders and are not descriptive of the actual types of the macro expansions. The actual types are implementation-defined and can be any integral type that would be the result of normal integral promotions for the corresponding type—e.g., if unsigned char is promoted to int, UCHAR_MAX might have type int.

All of the macros in <climits> expand to constant expressions.
