I have no problem with this. > and everyone is happy (he says optimistically). And I am as dubious as you are about this :) IMO, the biggest problem with round() is that it's TOO discoverable. People reach for it when what they really should be using is string formatting ("I want to display all these values to three decimal places"), and then sometimes get bitten when something doesn't actually display the way they think it will. When it's used correctly, it's usually fine.
