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!

Hi,

to convert a float to an int,
you need to explicitly cast the value with
4.8 $ int => int foo; // foo == 4
(as written here: https://chuck.cs.princeton.edu/doc/language/oper.html)

So you would do something like
pctPosInit $ int => int pctPosInitInt
pctPosInitInt/100*myBuf.samples() => myBuf.pos;
