Integer division by zero

[sylvanc]

Given that pony can't crash, how do we handle integer division by zero? Here are the choices:

1. Raise an error. This means any use of integer division or modulus must come in a try block or in a partial function.
2. Force the result to zero. So x / 0 or x % 0 results in 0.

I lean towards option 2. Both have the same performance cost (a conditional on the divisor) since catching SIGFPE (or the equivalent on Windows) would be problematic.

Definitely don't want to have to put every integer divide in a try block and catching SIGFPE would be terrible. So I think we should go with option 2.

I believe this is now implemented and I have recorded the decision on the wiki random information page.

Can we close this now Sylvan?

Yup, thanks! Went with option 2.
