How can I execute this math operation in PHP?
<p>I am trying to do this operation:</p>

<pre><code>$math = 1.30644 - 1.3063
</code></pre>

<p>I want the result to be the difference in this way:</p>

<p>1.4 (Which is 64,4 - 63) because I am dealing with PIPS. How can I achieve this result.</p>

<p>What I tried:</p>

<pre><code>$math = 1.30644 - 1.3063

echo $math; // output -0.3063 I want it to output 1.4
</code></pre>
