iPhone calculator

I know this sounds a bit geeky but:

On the iPhone calculator if you calculate log(0) it gives you minus infinity. (then you can use that to do e^-infinity and it gives you zero)

If you calculate tan(90) it gives you Error. Shouldn't that give you +infinity (by the same logic as the log(0))?

errrr, yes?

i would have thought they should both give an error
but tan(90) should not be infinity, it does not exist in any way

Nope. tan(90) = sin(90)/cos(90) = 1/0 = divide by zero error = undefined.

Not infinity.

So yeah I've been observing this same feature for quite some time as well and I'd like to mention that log(0) returns an error on version 9.2. I wonder why the change.

Really...
