A JavaScript equivalent of PHP's is_long

{% codeblock var/is_long.js lang:js https://raw.github.com/kvz/phpjs/master/functions/var/is_long.js raw on github %}
function is_long (mixed_var) {
  // From: http://phpjs.org/functions
  // +   original by: Paulo Freitas
  //  -   depends on: is_float
  // %        note 1: 1.0 is simplified to 1 before it can be accessed by the function, this makes
  // %        note 1: it different from the PHP implementation. We can't fix this unfortunately.
  // *     example 1: is_long(186.31);
  // *     returns 1: true
  return this.is_float(mixed_var);
}

Please note that php.js uses JavaScript objects as substitutes for PHP arrays, they are 
the closest match to this hashtable-like data structure. 

Please also note that php.js offers community built functions and goes by the 
[McDonald's Theory](https://medium.com/what-i-learned-building/9216e1c9da7d). We'll put online 
functions that are far from perfect, in the hopes to spark better contributions. 
Do you have one? Then please just:
