SET_IEEE_EXCEPTION - Sets floating-point exception indicator
As shipped in IRIX 6.5.19. Last changed in IRIX 6.5.19.
NAME SET_IEEE_EXCEPTION - Sets floating-point exception indicator SYNOPSIS SET_IEEE_EXCEPTION ([EXCEPTION=]exception) STANDARDS Fortran extension IEEE Standard for Binary Floating-point Arithmetic DESCRIPTION The SET_IEEE_EXCEPTION intrinsic subroutine sets the specified floating-point exception indicator. It accepts the following argument: exception Must be of an integer type that occupies a full word. It is an INTENT(IN) argument. If exception is an array, it must be 1-dimensional. The single argument in the scalar case, or each array element in the array case, must be set to one of the values represented by the following named constants: * IEEE_XPTN_INEXACT_RESULT * IEEE_XPTN_UNDERFLOW * IEEE_XPTN_OVERFLOW * IEEE_XPTN_DIV_BY_ZERO * IEEE_XPTN_INVALID_OPR * IEEE_XPTN_ALL (all exceptions in this list) The exception indicator specified by exception (or each element of exception) is set so it indicates that the exception has occurred. Using this subroutine to set an exception indicator does not cause the exception to be raised. SET_IEEE_EXCEPTION is an elemental subroutine. The name of this intrinsic cannot be passed as an argument. NOTES The IEEE intrinsic procedures use the named constants contained in a system module, so you must include the following statement in your program: USE FTN_IEEE_DEFINITIONS EXAMPLES The following example sets the divide by zero exception indicator so that the next time TEST_IEEE_EXCEPTION tests the indicator, it will indicate the exception has occurred: CALL SET_IEEE_EXCEPTION(IEEE_XPTN_DIV_BY_ZERO) SEE ALSO CLEAR_IEEE_EXCEPTION(3I), GET_IEEE_EXCEPTIONS(3I), TEST_IEEE_EXCEPTION(3I)
