WebOct 14, 2015 · You can think of a fixed-point integer as the numerator of a fraction, possibly with a bias applied. In your case, you want -1.0 to map to -INT_MAX, and 1.0 to map to INT_MAX (that is, 2**31 - 1 ). A couple of turns of the algebra crank gives us: fixed = int (flt * (INT_MAX/2)) Note that the rounding isn't perfect there.
