IEEE_GET_UNDERFLOW_MODE
Intrinsic Module Subroutine (Generic): Stores the current underflow mode. This is an impure subroutine.
Module
USE, INTRINSIC :: IEEE_ARITHMETIC
CALL IEEE_GET_UNDERFLOW_MODE (gradual)
gradual |
(Output) Must be logical scalar. The result is true if the current underflow mode is gradual (IEEE subnormals are allowed) and false if the current underflow mode is abrupt (underflowed results are set to zero). |
Example
Consider the following:
USE, INTRINSIC :: IEEE_EXCEPTIONS LOGICAL GRAD ... CALL IEEE_GET_UNDERFLOW_MODE(GRAD) IF (GRAD) THEN ! underflows are gradual ... ELSE ! underflows are abrupt ... END IF
