Some common square roots are defined as constants, to save the overhead of calculating them: M_SQRT2 = sqrt(2) M_SQRT3 = sqrt(3) M_SQRTPI = sqrt(pi) M_2_SQRTPI = 2 / sqrt(pi) M_SQRT_1_2 = sqrt(1/2) ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.135 (proxied: 217.33.116.130) ---- Manual Page -- https://php.net/manual/en/function.sqrt.php Edit -- https://main.php.net/note/edit/127301 Del: integrated -- https://main.php.net/note/delete/127301/integrated Del: useless -- https://main.php.net/note/delete/127301/useless Del: bad code -- https://main.php.net/note/delete/127301/bad+code Del: spam -- https://main.php.net/note/delete/127301/spam Del: non-english -- https://main.php.net/note/delete/127301/non-english Del: in docs -- https://main.php.net/note/delete/127301/in+docs Del: other reasons-- https://main.php.net/note/delete/127301 Reject -- https://main.php.net/note/reject/127301 Search -- https://main.php.net/manage/user-notes.php
