Enumeration constants of type std::float_round_style indicate the rounding style used by floating-point arithmetics whenever a result of an expression is stored in an object of a floating-point type. The values are:
Enumeration constants
| Name | Definition |
|---|---|
std::round_indeterminate | Rounding style cannot be determined |
std::round_toward_zero | Rounding toward zero |
std::round_to_nearest | Rounding toward nearest representable value |
std::round_toward_infinity | Rounding toward positive infinity |
std::round_toward_neg_infinity | Rounding toward negative infinity |
