Hi guys
I've been fighting with a function that uses some plugin to get numbers from some fields in a specific form.

After some time, I found some example code that added "* 1" to the value for treating the value as number. I mean:

        

         
 var total = jQuery("#myfield").val() + subTotal;
        

   

    
 var total = (jQuery("#myfield").val() * 1) + (subTotal * 1);
   

Why is this problem? Any reference? Any plugin that can solve this? Maybe a math plugin?
