    Not sure if this will help but please consider;

    Fr (frequency resolution) = 360000000/2^32 = 0.08381903171539306640625 Hz

    FTW = INT(Fo / Fr)
    FTW = INT(10000000 / 0.08381903171539306640625) = 119304647

    or using reciprocal multiplication (with a constant 1 / Fr = 11.9304647);

    FTW = INT(Fo * (1 / Fr))
    FTW = INT(10000000 * (11.930464711111111111111111111111)) = 119304647

    Good luck on your project...

    Cheerful regards, Mike, K8LH
