From: [EMAIL PROTECTED] Operating system: FreeBSD 4.5-RELEASE PHP version: 4.2.1 PHP Bug Type: Math related Bug description: pow() does not recognize integer numbers when cast as string
Here's code to replicate. Please see note below as to why these are string values. <?php $base="2"; $exp="8"; echo pow($base,$exp); ?> Gives me the error: [28-May-2002 12:48:18] PHP Warning: Invalid argument(s) passed to pow() in (....)/editMatrix.inc on line 74 --- This may seem a low-priority issue, however, in a matrix project I'm working on the base/exponents are usually stored in a database, and the functions to retrieve them are usually typecast as strings when fetch()'ed and stored in an array. I have to assign temporary variables with the value of the base and exponent re-assigned using settype([$tmp_base|$tmp_exp],"integer") in order to get pow() to work. This does not seem like a 'clean' solution, could perhaps pow() be a little less strict as far as it's types, or is php heading towards stricter casting for all functions? -- Edit bug report at http://bugs.php.net/?id=17492&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=17492&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=17492&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=17492&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=17492&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=17492&r=support Expected behavior: http://bugs.php.net/fix.php?id=17492&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=17492&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=17492&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=17492&r=globals
