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 
   };

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.

See numeric_limits::has_denorm for an example in which the values of this enumeration may be accessed.
