Doing it that way you can't. One is a string, the other's a number. You'd
have to first convert the fraction into it's decimal representation. You
could prolly write a function to do that. Something like this would work:
str = '3/8';
function convertDecimal(str) {
Thanks Barney... That did the trick.

That's cool Barney. I didn't know it would be quite that efficient. Any
performance hits using eval?

The latt
It seems to me you have two choices. You can do it as a string (by
converting the 20 to a string and adding a space and the fraction) or as
a number, which will give you a decimal. Which are you trying to
accomplish?

The latter operand will evaluate the string as if it were javascript
(i.e. do 3 / 8), which will give you the floating-point equivalent of
the fraction, which can then be added to the integer (giving 20.375).

Try:
var num = 20.0;
var frac = 3/8;
var DBWTemp = (num + frac);
document.write(DBWTemp);
Should work.

take 3/8 out of quotes. it's not a string. it's a number.
you'll get 20.375.
or were you looking for 20 3/8?
