Use phpjs functions as required.

exports.is_int=require("./is_int");
module.exports=function(){ return is_integer.apply(exports,arguments) };

function is_integer(mixed_var) {
  //  discuss at: http://phpjs.org/functions/is_integer/
  // original by: Paulo Freitas
  //  depends on: is_int
  //        note: 1.0 is simplified to 1 before it can be accessed by the function, this makes
  //        note: it different from the PHP implementation. We can't fix this unfortunately.
  //   example 1: is_integer(186.31);
  //   returns 1: false
  //   example 2: is_integer(12);
  //   returns 2: true

  return this.is_int(mixed_var);
