Intrinsic Module Subroutine (Generic): Restores the state of the floating-point environment. This is an impure subroutine.

Module

USE, INTRINSIC :: IEEE_EXCEPTIONS

CALL IEEE_SET_STATUS (status_value)

status_value

(Input) Must be scalar and of type TYPE (IEEE_STATUS_TYPE). Its value must be set in a previous invocation of IEEE_GET_STATUS.

Example

Consider the following:

USE, INTRINSIC :: IEEE_EXCEPTIONS ! Can also use IEEE_ARITHMETIC
TYPE (IEEE_STATUS_TYPE) STATUS
...
CALL IEEE_GET_STATUS (STATUS) ! Stores the floating-point status
CALL IEEE_SET_FLAG (IEEE_ALL,.FALSE.) ! Sets all flags to be quiet
...
CALL IEEE_SET_STATUS (STATUS) ! Restores the floating-point status
