You can use the parseInt   function to convert the string to a number  e g   parseInt     elem   css  top       Update   as suggested by Ben   You should give the radix too   parseInt     elem   css  top    10     Forces it to be parsed as a decimal number  otherwise strings beginning with  0  might be parsed as an octal number  might depend on the browser used
