NAME

	IEEEDPTst -- compare IEEE double precision value to 0.0

SYNOPSIS

	  c   = IEEEDPTst(  y  );
	  d0		  d0/d1
	double	y;
	long	c;

FUNCTION

	Compare y to 0.0, set the condition codes for less than, greater
	than, or equal to 0.0.  Set the return value c to -1 if less than,
	to +1 if greater than, or 0 if equal to 0.0.

INPUTS

	y -- IEEE double precision floating point value

RESULT

	c = 1	cc = gt		for (y > 0.0)
	c = 0	cc = eq		for (y == 0.0)
	c = -1  cc = lt		for (y < 0.0)
