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
