The division by a constant D is equivalent to the multiplication by its reciprocal. 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). WebMar 15, 2012 · Fixed-point math is most commonly used for systems that lack an FPU or when you need a few more ounces of performance or precision than the standard floating point types can provide (hint: this is rare). Fixed-point values are much less convenient to work with than floating point values. You should only use them as a last resort.
