Re: [Python-Dev] Not-a-Number

I'm sorry for my lack of clarity. I'm referring to functions which potentially produce NANs, not the exceptions themselves. A calculation which might have produced a (quiet) NAN as the result instead raises an exception (which I'm treating as equivalent to a signal).

Yes, it produces a Python exception, which is not a Python NaN. If you want to talk about “signalling NaNs”, you'll have to distinguish that (every time!) so you're not misunderstood as referring to a Python NaN object. -- \ “It's my belief we developed language because of our deep inner | `\ need to complain.” —Jane Wagner, via Lily Tomlin | _o__) | Ben Finney
