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
