std::float_denorm_style

STD：浮动[医]脱诺姆[医]风格

Defined in header ​​
enum float_denorm_style { denorm_indeterminate = -1, denorm_absent = 0, denorm_present = 1 };​​

类型枚举常数std::float_denorm_style通过浮点类型指示对低于正常值的支持。

枚举常数

NameDefinition
std::denorm_indeterminateSupport of subnormal values cannot be determined
std::denorm_absentThe type does not support subnormal values
std::denorm_presentThe type allows subnormal values

另见

has_denorm staticidentifies the denormalization style used by the floating-point type (public static member constant)
