WebApr 8, 2012 · Sorted by: 93. The idea behind fixed-point arithmetic is that you store the values multiplied by a certain amount, use the multiplied values for all calculus, and divide it by the same amount when you want the result. The purpose of this technique is to use integer arithmetic (int, long...) while being able to represent fractions. WebHow to do the conversion? fixed / 65536.0 is correct and easy to understand. (fixed >> 16) + (fixed & 0xffff) / 65536.0 Is equivalent to the above for positive integers, but slower, and harder to read. You're basically using the distributive law to separate a single division into two divisions, and write the first one using a bitshift.
