I'm happy to work through one at a time (or maybe you'd like to fix some?), I don't really want to do them all in one update. I used exp() to make sure that I was doing the right thing. Quite a few of the tests would also need changing (because I worked around this for a while). I think sin() and cos() at least are wrong. I've also got bugs pending in number_format() and hypot() - which *might* be the same issue.

Only fix the exp() sounds wrong to me... ------------------------------------------------------------------------ [2008-02-11 14:23:35] iliaa@php.net Go ahead and apply the patch to the code & the test. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
