round up with php

always round up to 2 decimal places

[kermey]

This is an odd problem. If my script has an amount, say 0.61222, I need to round it up to the nearest 2 decimal place. round() will round it down (properly) but i need to always round up so 0.61222 would become 0.62. ceil() doesnt work, it rounds the whole lot up to 1. Any ideas?

You can use number_format to format decimal places. Dont think this rounds the decimal number up though.

ceil($x*100)/100

$x = 0.1612213

$x = ceil(100 * $x)/100;

is there an echo in here? :-)

Stretch out your math brain with this one:

function roundup($x,$places){
$cent=pow(10,$places);
return ceil($x*$cent)/$cent;
}
