If you want to do number stuff if the value is a number or a string representation of a number you can do the following:

if (!isNaN(myVar)){//myVar is either a number or a string representing a number
    myNumericVar = +myVar;//convert myVar to number if necessary
    //do number stuff
} else {
   //do non-numeric stuff
}
