Hi,
For is_float i use this version:
<pre><code>
function is_float(n) {
  return n===+n &amp;&amp; n!==(n|0);
}
</code></pre>
 - is_float() doesn't always work if you are validating form input. This is because form inputs are strings, even if the user typed a number.

version in one line:
<pre><code>
return typeof mixed_var == 'number' ? !!(mixed_var % 1) : false;
</code></pre>

Nevermind my comments, I just now noticed in the docs the text about the 1.0 issue. :P
