set_ieee_exceptions(3I)

NAME
     SET_IEEE_EXCEPTIONS - Restores the caller's floating-point status
     prior to exiting a procedure

SYNOPSIS
     SET_IEEE_EXCEPTIONS ([STATUS=]status)

IMPLEMENTATION
     UNICOS/mk and IRIX systems

     CRAY T90 systems that support IEEE floating-point arithmetic

STANDARDS
     CF90 and MIPSpro 7 Fortran 90 compiler extension to Fortran 90

     IEEE Standard for Binary Floating-point Arithmetic

DESCRIPTION
     The SET_IEEE_EXCEPTIONS intrinsic subroutine restores the caller's
     floating-point status just before exiting a procedure.  It accepts the
     following argument:

     status         Must be scalar and of an integer type that occupies a
                    full word.  It is an INTENT(IN) argument.

     On CRAY T90 systems that support IEEE floating-point arithmetic, the
     bits in status that represent exception flags are stored into the
     appropriate bits of SR0.  On other architectures, the flags are stored
     into the appropriate flag bits of memory word(s)/register(s) that
     record the floating-point state.

     The value of status is assumed to have been set by
     GET_IEEE_STATUS(3I).

     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 one of the following statements in
     your program:

     * On UNICOS and UNICOS/mk systems:  USE CRI_IEEE_DEFINITIONS

     * On UNICOS, UNICOS/mk, and IRIX systems:  USE FTN_IEEE_DEFINITIONS

     The CRI_IEEE_DEFINITIONS module is obsolescent.  It will be removed
     for the CF90 4.0 release.

EXAMPLES
     See the example on CLEAR_IEEE_EXCEPTION(3I).
