Limit number of places in php

Question

i am wondering how to limit some numbers etc:
This number: 90.909090909091
just to: 90.90

I am using math here,

$var1share = $adamage / ($adamage + $ddamage) * 100;

So, i want $varshare output to be in format: 90.90, no: 90.909090909091, if you understand...
Is it possible? Thanks

Use the [number_format()](http://www.php.net/manual/en/function.number-format.php) function or [sprint()](http://www.php.net/manual/en/function.sprintf.php) when echoing the value — Mark Baker, Feb 07 '15 at 23:09

The documentation links in my comment should help, and provide plenty of examples — Mark Baker, Feb 07 '15 at 23:10

Use round() function:

$var1share = $adamage / ($adamage + $ddamage) * 100;
$var1share = round(var1share, 2);

disagree. round returns also a float, so numeric unstable. sprintf returns a string. – Aitch Feb 07 '15 at 23:14
