Eliminate decimal points of source text when tied to rotation?
I have a text layer with the source text pick-whipped to another layers rotation value. I want the source text to update with the number of degrees when I rotate the layer.
It works fine but it adds 13 numbers after the decimal point. Is there a way to update the source text expression so that it only reads one number after the decimal point instead of 13?
Thank you for any help.

myNumber = 23.3453255243697978; round(myNumber, 2); function round(aNum, dP) { return(Math.round(aNum*Math.pow(10, dP))/Math.pow(10, dP)); }you can also use myNumber.toFixed(2) but After Effects doesn’t always recognise numbers as numbers, in which case this will throw an error. This version will also pad the decimal places with zeros, which the above function won’t.

WOW! Thanks for the quick response Ben. That worked perfectly.
P.S. Amazing Demo Reel

Ben, do you mind explaining that expression? What each element of the function means? Is there a way to make it a simpler expression? I’d like something short that is easy to remember. If possible.
Thanks!
