NAME

	SPTst - Compares a float against zero (0.0).

SYNOPSIS

	result = SPTst(fnum)
	D0	       D1
	int SPTst(float fnum);

FUNCTION

	Accepts a floating point number and returns the condition
	codes set to indicate the result of a comparison against
	the value of zero (0.0).  Additionally, the integer functional
	result is returned.

INPUTS

	fnum 	- floating point number.

RESULT

	Condition codes set to reflect the following branches:
		EQ - fnum =  0.0
		NE - fnum != 0.0
		PL - fnum >= 0.0
		MI - fnum <  0.0
	Integer functional result as:
		+1 => fnum > 0.0
		-1 => fnum < 0.0
		 0 => fnum = 0.0

BUGS

	None.
