I am writing a script that is dividing numbers

as a result I can get a very long  number as it contains many numbers after
the decimal point

I know you can use floor() to drop everything after the decimal point and
ceil() to round 13.2  up to 14
but how  can I get

2.8603515625  to be rounded to 2.86 ?

I believe the round function does just that with its second parameter.

If you actually wanted to use floor or ceil then just move the decimal
point with the power of ten.

$Num = (Floor($Num * 100)/100)

Hey Will,

Try the round function (good in PHP 3 and 4).

<?php
$num1 = 2.8603515625;
$num2 = round( $num1, 2);
echo $num2;
?>
