#41108 [Fbk->Opn]: pow() doesn't handle negative exponents

ID: 41108 User updated by: jack dot nerad at comcast dot net Reported By: jack dot nerad at comcast dot net -Status: Feedback +Status: Open Bug Type: Feature/Change Request PHP Version: 6CVS-2007-04-17 (CVS) New Comment: Now that's turnaround time! I didn't even have to upgrade to the latest version! :) Actually, I was looking for how to do exponentiation in the docs, found pow(), and read: "Note: PHP cannot handle negative exps." at http://us.php.net/manual/en/function.pow.php There's pretty much only one way to read that, I think, so I didn't bother to look for features explicitly ruled out by the docs. In addition, there are a bunch of notes with hacks on how to get around the no negative exponents 'feature?' (shrug) Close this feature request, or whatever. Maybe change it to a bug in the docs?

Every other respectable language that has half the vocabulary that PHP has can handle negative exponents. Heck, even the windows calculator can handle negative exponents. Please. Mature and refine the language to include this ability. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41108&edit=1
