SET_IEEE_EXCEPTIONS - Restores the caller's floating-point status
prior to exiting a procedure
SET_IEEE_EXCEPTIONS ([STATUS=]status)
UNICOS/mk and IRIX systems
CRAY T90 systems that support IEEE floating-point arithmetic
CF90 and MIPSpro 7 Fortran 90 compiler extension to Fortran 90
IEEE Standard for Binary Floating-point Arithmetic
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.
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.
See the example on CLEAR_IEEE_EXCEPTION(3I).
