You can use the parseInt() and parseFloat() methods. Notice that extra letters following a valid number are ignored, which is kinda wierd but convenient at times.
parseInt("100") ==> 100 parseFloat("98.6") ==> 98.6 parseFloat("98.6 is a common temperature.") ==> 98.6 parseInt("aa") ==> Nan //Not a Number parseInt("aa",16) ==> 170 //you can supply a radix or base
