enums
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:
enum float_denorm_style {
denorm_indeterminate = -1,
denorm_absent = 0,
denorm_present = 1 };
Return Value
The enumeration returns:
denorm_indeterminate
if the presence or absence of denormalized forms cannot be determined at translation time.denorm_absent
if denormalized forms are absent.denorm_present
if denormalized forms are present.
Example
See numeric_limits::has_denorm for an example in which the values of this enumeration may be accessed.
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.
Example
See numeric_limits::round_style for an example in which the values of this enumeration may be accessed.
