As a workaround, right now you can round numbers using the two-step calculation shown in this calc: http://new.instacalc.com/1174. (In that calc, you can click on a red answer to see its calculation if the calculation is hidden). However, I agree that it would be nice if you could achieve the same affect with an extra parameter to the round() function, so "round(2/3, 3)" would return "0.667". Although there is the question as to whether the second parameter means the number of significant digits or the number of decimals - my workaround assumed you meant significant digits.
