<br>
there's no other sane way to handle division by 0 in the audio domain since the result must be a number and there are only two options: output 0 or some ridiculously large number (which would be quite dangerous).<br>
Pd *could* handle it differently in the control domain, but why? <br>
as Matt said: just don't divide by 0 :-)<br>

<span class="">Just don’t allow your function to blow up in the first place. <br>

I have a function which blows up at a certain point, moves to infinity.<br>
In this case, it is basically 1/0.<br>
<br>
I was a little surprised to find that 1/0 = 0 (according to Pd).<br>
I was expecting NaN, or an overflow condition would could be trapped.<br>
<br>
So what I have to do is examine the *input* for the values<br>
which will blow up my function, and set a flag. While this<br>
is easy in this single case, it is awkward in the general case.<br>
<br>
This seems somewhat broken to me.<br>
Is this a bug?<br>
<br>
Thanks<br>
