Round number down the to the nearest hundredth using php

Question

I'm probably not looking hard enough but the common question about php rounding is rounding up, not down.

For example I am trying round this..

<?php $roundDown = 768; ?>

Down to..

<?php var_dump($roundDown) /* 700 */ ?>

Whats the simplest method to do this, or is it because the number is closer to 800 that it's not technically rounding?

Whats the function that I need to do this if it's not rounding?

A little point in the right direction would be much appreciated.

Frankly, I think the easiest way to do this is change the last two digits in the number to 00, that will work every time. — Russ J, Feb 18 '19 at 04:07

You can try ceil() and floor() function.

 echo floor(768 / 100) * 100;  // Output:700
 echo ceil(768 / 100) * 100;  // Output:800
