| Thanks Byron, Here's what finally worked: // get the value we want n = thisComp.layer("shape").transform.rotation.value; // add two zeros, and make it an unsigned string -- we'll add the negative back later if it's supposed to be negative nScaled = Math.abs(Math.round(n * 100)); s = "" + nScaled.toString(); // pad low values with leading zeros to ensure at least 3 digits after we move the decimal point while (s.length < 3) s = "0" + s; // if it was negative, add the - sign back if (n<0) s = "-" + s; // insert the decimal place before the last two decimal places s = s.substr(0,s.length-2) + "." + s.substr(s.length-2,s.length) Thanks to Walter Soyka over on the AE Creative Cow board.

Use this instead of your existing code. Doesn't deal with the negative sign, though; written hastily.
