Add a decimal after two first numbers
<p>I am generating some data of latitude and longitude with <code>rand(10000000, 3000000);</code> for example. But I need to calculate distance between two locations, so basically I need to convert my result, for example <code>22049256</code> to <code>22.049256</code> in order to pass to my function.</p>

<p>How can I achieve this most effectively with using least amount of resources?</p>

<p>TL;DR
I have integer <code>22049256</code>, needs to be converted to float <code>22.049256</code>.</p>
