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:

[edit] 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
