Another approach for when the point is known (or fixed) is the fixed point technique. A variation of this algorithm is described as algorithm 3.41 on page 104 of the Guide.

WebApr 3, 2016 · Fixed point generally doesn't provide much of an advantage in speed though, because of its limited representation range: how many bits would you need to represent 1.7E+/-308 with 15 digits of precision, the same as a 64-bit double? If my calculations are correct, you'd need somewhere around 2024 bits.

WebFeb 16, 2016 · First assume you multiply two fixed-point numbers. Let's call them X and Y, first containing Xf fractional bits, and second Yf fractional bits accordingly. If you multiply those numbers as integers, the LSB Xf+Yf bits of the integer result could be treated as fractional bits of resulting fixed-point number (and you still multiply them as integers). chiropody costs ukWebA fixed-point machine, it can be used to process algorithms traditionally implemented in floating-point math.
