Function/Subroutine Documentation
   LOGICAL function slaisnan (realSIN1, realSIN2)
       SLAISNAN tests input for NaN by comparing two arguments for inequality.


	    This routine is not for general use.  It exists solely to avoid
	    over-optimization in SISNAN.

	    SLAISNAN checks for NaNs by comparing its two arguments for
	    inequality.  NaN is the only floating-point value where NaN != NaN
	    returns .TRUE.  To check for NaNs, pass the same variable as both

	    A compiler must assume that the two arguments are
	    not the same variable, and the test will not be optimized away.
	    Interprocedural or whole-program optimization may delete this
	    test.  The ISNAN functions will be replaced by the correct
	    Fortran 03 intrinsic once the intrinsic is widely available.


		     SIN1 is REAL


		     SIN2 is REAL
		     Two numbers to compare for inequality.
