Multiplication in PHP
<p>I have to do a calculation, here is a simplification of what I am trying to achieve:</p>

<pre><code>$box['dim1'] = 1;
$box['dim2'] = 1;
$box['dim3'] = 1;

$volume = (($box["dim1"]/100) * ($box["dim2"]/100) * ($box["dim3"]/100));

echo $volume;
</code></pre>

<p>In this case I see:</p>

<pre><code>1.0E-6
</code></pre>

<p>Rather than 0.000001 as I would expect.</p>

<p>This is a rather extreme example and dim1, dim2 and dim3 are unlikely to ever all equal 1 but I need the value of $volume to be a number as this is passed to a 3rd party API and they don't like 1.0E-6.</p>

<p>Is there anyway I can get $volume to equal 0.000001 and not 1.0E-6?</p>
