NAME
        IEEESPDiv -- divide one single precision IEEE by another

   SYNOPSIS
          x   = IEEESPDiv(  y  ,  z  );
         d0                d0    d1

        float   x,y,z;

   FUNCTION
        Compute x = y / z in IEEE single precision.
        Note that the Motorola fast floating point Div routine reverses
        the order of the arguments for the C interface, although the
        dividend is still in d0 and the divisor is in d1.

   INPUTS
        y -- IEEE single precision floating point value
        z -- IEEE single precision floating point value

   RESULT
        x -- IEEE single precision floating point value
