#44092 [Fbk]: exp() function returns incorrect result if passed hex

ID: 44092 Updated by: bjori@php.net -Summary: zoe Reported By: zoe@php.net Status: Feedback Bug Type: *Math Functions Operating System: Linux 32 PHP Version: 5.3CVS-2008-02-10 (CVS) New Comment: (fix summary) Previous Comments: ------------------------------------------------------------------------ [2008-02-12 07:36:16] zoe@php.net commited fix to /ext/standard/math.c and /ext/standard/tests/math/exp_error.phpt in PHP5.3 and PHP 5.2 ------------------------------------------------------------------------ [2008-02-11 16:22:30] zoe@php.net Felipe - I think they should probably all change. 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. Zoe ------------------------------------------------------------------------ [2008-02-11 16:07:30] felipe@php.net Hello Ilia, in this case, should all math functions in ext/standard/ use the new parsing parameter, no? 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. ------------------------------------------------------------------------ [2008-02-10 17:27:40] zoe@php.net If this patch goes in, the test exp_error.phpt will need a small change too. I'm happy to do that. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
