I am linking one layers rotation to a text layers source text.

How do I modify the simple expression to limit the decimal to two =
places, and at the same time make all integers two digits so 0 - 9 are =
00, 01, 02,...?

Something like this but that adds two decimal places to the number:

//--Expression begins
nums =3D thisComp.layer("shape").transform.rotation;
amtOfZeroes =3D 2;
//--Do not modify below this line
isNeg =3D false;
if(nums < 0)
{
nums =3D Math.abs( nums );
isNeg =3D true;
}
sVal =3D Math.round( nums ) + "";
while(sVal.length < amtOfZeroes)
{
sVal =3D "0" + sVal;=20
}
if(isNeg)
sVal =3D "-" + sVal;

sVal
//--Expression ends


Thanks, James
