note 46408 added to language.types.float

If you're used to shift numbers to left (or right), like <?php echo (double)(1 << ($n * 10)); ?> you'd better change it for something more secure, like <?php echo pow(2, $n * 10); ?> 'cause sometimes PHP seem to evaluate it using integer values ¬ ¬ PS It doesn't matter if $n is an integer or not, neither if you add as many '(double)' casts in every position you could think of. ---- Manual Page -- http://www.php.net/manual/en/language.types.float.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+46408 Delete -- http://master.php.net/manage/user-notes.php?action=delete+46408&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+46408&report=yes Search -- http://master.php.net/manage/user-notes.php
