title: Round number down the to the nearest hundredth using php
body: <p>I'm probably not looking hard enough but the common question about php rounding is rounding up, not down.</p>
  
  <p>For example I am trying round this..</p>
  
  <pre><code>&lt;?php $roundDown = 768; ?&gt;
  </code></pre>
  
  <p>Down to..</p>
  
  <pre><code>&lt;?php var_dump($roundDown) /* 700 */ ?&gt;
  </code></pre>
  
  <p>Whats the simplest method to do this, or is it because the number is closer to 800 that it's not technically rounding?</p>
  
  <p>Whats the function that I need to do this if it's not rounding?</p>
  
  <p>A little point in the right direction would be much appreciated.</p>
