[PD] 1 / 0 = 0?

[Christof Ressi]

Hi William,
 
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).
Pd *could* handle it differently in the control domain, but why? 
as Matt said: just don't divide by 0 :-)

Christof

Just don’t allow your function to blow up in the first place.

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