title: How can I check if a value is of type Integer?
body: <p>I need to check if a value is an integer. I found this: <a href="https://stackoverflow.com/questions/4727569/how-to-check-whether-input-value-is-integer-or-float">How to check whether input value is integer or float?</a>, but if I'm not mistaken, the variable there is still of type <code>double</code> even though the <strong><em>value</em></strong> itself is indeed an <code>integer</code>.</p>
