Defines the class template numeric_limits and two enumerations concerning floating-point representations and rounding.
Requirements
Header: <limits>
Namespace: std
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.
Members
Enumerations
| Name | Description |
|---|---|
| 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
| Name | Description |
|---|---|
| numeric_limits Class | The class template describes arithmetic properties of built-in numerical types. |
