note 74793 added to function.rand

I was kind of surprised that PHP did not have a built-in floating point random number function. So I created my own: <? // Floating point random number function // April 2007, René W. Feuerlein function fprand($intMin,$intMax,$intDecimals) { if($intDecimals) { $intPowerTen=pow(10,$intDecimals); return rand($intMin,$intMax*$intPowerTen)/$intPowerTen; } else return rand($intMin,$intMax); } // Example of fprand function for($i=0; $i<=5; $i++) { echo "Three random numbers with $i decimals are: "; for($ii=1; $ii<=3; $ii++) echo fprand(1,10,$i).' '; echo '<br>'; } ?> ---- Server IP: 69.39.81.135 Probable Submitter: 70.11.185.195 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/74793 Del: integrated -- https://master.php.net/note/delete/74793/integrated Del: useless -- https://master.php.net/note/delete/74793/useless Del: bad code -- https://master.php.net/note/delete/74793/bad+code Del: spam -- https://master.php.net/note/delete/74793/spam Del: non-english -- https://master.php.net/note/delete/74793/non-english Del: in docs -- https://master.php.net/note/delete/74793/in+docs Del: other reasons-- https://master.php.net/note/delete/74793 Reject -- https://master.php.net/note/reject/74793 Search -- https://master.php.net/manage/user-notes.php
