Since the denominator is constant, so is its reciprocal (1/D). Thus it is possible to compute the value of (1/D) once at compile time, and at run time perform the multiplication N·(1/D) rather than the division N/D. In floating-point arithmetic the use of (1/D) presents little problem, but in integer arithmetic the reciprocal will always evaluate to zero (assuming D > 1). ct dmv order new platesWebJun 8, 2011 · A fixed-point math library will have fixed-point multiplication functions that handle this better.
