Defines the template class numeric_limits and two enumerations concerning floating-point representations and rounding.
Syntax
#include <limits>
Remarks
Explicit specializations of the numeric_limits class describe many properties of the fundamental types, including the character, integer, and floating-point types and bool that are implementation defined rather than fixed by the rules of the C++ language. Properties described in <limits> include accuracy, minimum and maximum sized representations, rounding, and signaling type errors.
Enumerations
| float_denorm_style | The enumeration describes the various methods that an implementation can choose for representing a denormalized floating-point value — one too small to represent as a normalized value: |
| float_round_style | The enumeration describes the various methods that an implementation can choose for rounding a floating-point value to an integer value. |
Classes
| numeric_limits Class | The template class describes arithmetic properties of built-in numerical types. |
