Is there an everyday practical application of is_infinite() in PHP?
<p>I was having a look at all of PHP's math functions and noticed there's an is_infinite() function that returns wether or not the supplied number is infinite.
I'm curious wether there happens to be some widely used application for this in everyday web development outside of the scientifical field.</p>

<p>I'm sorry if this is too much of a hypothetical question but I reckon it could be interesting to know if there was.</p>
