float_round_style
The enumeration describes the various methods that an implementation can choose for rounding a floating-point value to an integer value.
enum float_round_style {
round_indeterminate = -1,
round_toward_zero = 0,
round_to_nearest = 1,
round_toward_infinity = 2,
round_toward_neg_infinity = 3
};
Return Value
The enumeration returns:
round_indeterminate if the rounding method cannot be determined.
round_toward_zero if the round toward zero.
round_to_nearest if the round to nearest integer.
round_toward_infinity if the round away from zero.
round_toward_neg_infinity if the round to more negative integer.
