[SOLVED] PHP Division rounding to 2 decimal places?

[Padgoi]

Hi, I have this function but it's displaying a VERY long number.  I want to limit the number to 2 decimal places.  How would I go about doing this?  Any help is appreciated.

 

$total = $field / $get_topics[0];
$this->output .= "\t<td><font face=arial size=1/>$total</font></td>\n";

 

Thanks!

number_format

 

EDIT: Better yet, you can use money_format.

round() or number_format().

Sorry guys, my PHP is kinda weak.  I'm trying this but it's not working.

 

$total = $field / $get_topics[0];
round($total, 2);
$this->output .= "\t<td><font face=arial size=1/>$total</font></td>\n";

 

Where exactly do I put the round() function?

What do you mean PHP is weak? You just called a function without storing the value.

 

$total = round($field / $get_topics[0]);
$this->output .= "\t<td><font face=arial size=1/>$total</font></td>\n";

<?php
$total = $field / $get_topics[0];
$total = round($total, 2);
$this->output .= "\t<td><font face=arial size=1/>$total</font></td>\n";

Oops, typo there. My point was it's not a PHP issue, but logic or programming in general. If you call a function that returns a value, but you don't store it in a variable, nothing happens.
