The IEEE_FEATURES module contains derived data types that include named constants for controlling the level of support, and intrinsic module procedures.
The derived types in the intrinsic modules have components that are private. The IEEE_FEATURES intrinsic module supports specification of essential IEEE features. It defines the following derived types:
IEEE_FEATURES_TYPE: Specifies IEEE features. Its values are the following named constants:
IEEE_DATATYPE |
IEEE_INF |
IEEE_DIVIDE |
IEEE_NAN |
IEEE_ROUNDING |
IEEE_INEXACT_FLAG |
IEEE_SQRT |
IEEE_INVALID_FLAG |
IEEE_DENORMAL |
IEEE_UNDERFLOW_FLAG |
IEEE_HALTING |
IEEE_STATUS_TYPE: Saves the current floating-point status.
