note 30363 added to function.sqrt

It's accualy spelled "Pythagorean Theorem." I would also like to bring something to the attention of the people who want to use this fuction for that specific job, that is to use the shorter experimental function called hypot()... "hypot (PHP 4 >= 4.1.0) hypot -- Returns sqrt( num1*num1 + num2*num2) Description float hypot ( float num1, float num2)" for more information, see http://www.php.net/hypot -- http://www.php.net/manual/en/function.sqrt.php http://master.php.net/manage/user-notes.php?action=edit+30363 http://master.php.net/manage/user-notes.php?action=delete+30363 http://master.php.net/manage/user-notes.php?action=reject+30363
