Previous Comments: ------------------------------------------------------------------------ [2002-05-28 15:51:01] joe@intware.tv 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 this bug report at http://bugs.php.net/?id=17492&edit=1
