var bar=int((freq+0.001)*10)-int(freq)*10; The 0.001 ensures we get the proper number since 'int' truncates and doesn't round. For example, 111.70 is stored internally as 111.69999... since base 2 and base 10 don't play well together below the decimal point. int((111.699999...)*10) returns 1116 when what was expected and desired was 1117. 0.001 is large enough to correct the result but small enough not to push us to the next station, station spacing is assumed at 0.05. (The same problem exists in C++.)
