<br>
The ChucK language has a cast operator '$' which might come in handy in this situation<br>
<br>
(pctPosInit/100*myBuf.samples()) $ int => myBuf.pos;<br>
<br>
Cheers,<br>

<br>
to convert a float to an int,<br>
you need to explicitly cast the value with<br>
4.8 $ int => int foo; // foo == 4<br>
(as written here: <a href="https://chuck.cs.princeton.edu/doc/language/oper.html" rel="noreferrer" target="_blank">https://chuck.cs.princeton.edu/doc/language/oper.html</a>)<br>
<br>
So you would do something like<br>
pctPosInit $ int => int pctPosInitInt<br>
pctPosInitInt/100*myBuf.samples() => myBuf.pos;<br>
<br>
