IEEE_SET_HALTING_MODE

Elemental Module Intrinsic Function (Generic): Controls halting or continuation after an exception. This is a pure subroutine.

Module

USE, INTRINSIC :: IEEE_EXCEPTIONS

CALL IEEE_SET_HALTING_MODE (flag, halting)

flag

(Input) Must be of type TYPE (IEEE_FLAG_TYPE). It specifies one of the following IEEE flags:

IEEE_DIVIDE_BY_ZERO, IEEE_INEXACT, IEEE_INVALID, IEEE_OVERFLOW, or IEEE_UNDERFLOW

halting

(Input) Must be scalar and of type logical. If the value is true, the exception specified in flag will cause halting; otherwise, execution will continue after this exception.

Example

Consider the following:

USE, INTRINSIC :: IEEE_EXCEPTIONS 
LOGICAL HALT
...
CALL IEEE_GET_HALTING_MODE(IEEE_INVALID, HALT)  ! Stores the halting mode
CALL IEEE_SET_HALTING_MODE(IEEE_INVALID, .FALSE.) ! Stops halting
...
CALL IEEE_SET_HALTING_MODE(IEEE_INVALID, HALT)  ! Restores halting
