status.i4.v = math_exception_check()

	This routine returns and clears the last condition trapped by
	math_exception_establish.  If no trap has occurred, a value
	of SS__NORMAL is returned.  Nested calls to this facility can
	result in errors occurring in one layer being detected and
	cleared in another.  Therefore, this routine should be called
	immediately after every mathematical expression so that error
	information is not lost.

	This function returns status values as follows:

	SS__NORMAL		no trap has occurred
	SS__FLTDIV_F		floating divide by zero
	SS__FLTOVF_F		floating overflow
	SS__FLTUND_F		floating underflow
	SS__INTOVF		integer overflow
	SS__INTDIV		integer divide by zero
	MTH__FLOOVEMAT		floating overflow in math library
	MTH__LOGZERNEG		logarithm of zero or a negative value
	SS__xxx			other trapped error condition

	This function requires the following include files:

	cbslib_h, ssdef_h, mthdef_h
