I would suggest that you call Math.round() before casting, as to prevent undesirable effects: notice that in the example sent by ermina, 4.8 rounds down to 4 when cast to int, which could cause miscalculations *depending on your use case*. The previous example would look something like this if we used Math.round():
Math.round(pctPosInit) $ int => int pctPosInitInt; pctPosInitInt/100*myBuf.samples() => myBuf.pos; Best regards!
