You could simply create a jquery plugin to use instead of val() that would do this. Here I create the function nval() to use instead of val() when fetching a elements value.

$.fn.nval = function() {
   return Number(this.val())
};

Then in your code just use the following to get the value as a number

$('#elementID').nval()
