WebFor the integer part, just ignore the upper bits, or do the same as if it overflowed (since you had a 16.16 format and now you want 8.8). Here's an example: // multiply fixed point number x with y, both are 8.8 format // we want the result to be of 8.8 format too, so we need to shift right by 8 r = (x * y) >> 8. WebArithmetic operations on floating point numbers consist of addition, subtraction, multiplication and division. The operations are done with algorithms similar to those used on sign magnitude integers (because of the similarity of representation) — example, only add numbers of the same sign. If the numbers are of opposite sign, must do subtraction.
