float fsub (float x, float y); |
Floating point substraction.
fsub returns the difference of floating point arguments x and y.
This routine performs the same operation as the C '-'
operator applied to floating
point operands, but it is kept here for backwards compatibility.
At the fundamental level, fsub is exactly the same routine as
bcdsub.
