fsub Function (ROM Call 0xB7*)

timath.h

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.
