Limiting decimal length

[Praetorian]

I wrote a math script, and I was wondering if someone could tell me how to limit the length of numbers after the decimal point. (Ie... 2.01 instead of 2.019943234 etc).Thanks.

//round($number, $decimalplaces);//For example$number = 2.019943234;echo round($number, 2); //Will echo 2.02

[jhecht]

function roundOff($int,$length){  return substr($int,0,(strrpos($int,".")+$length) );}

Should also do it(if you dont want the number rounded off.

Or

$number = 2.019943234;$number *= 100;$number = floor($number);$number /= 100;echo $number; //Will echo 2.01
