    "I have to admit I never pay attention to these fine points in my own
    software. Since Tinyac and Lunar3 both have selectable precision, I
    assume the user will use, say, .01 precision if "tenths" are critical."

    This may be beneficial in some cases, but it also has the potential of aggravating an error through the effect of double rounding when a user selects .01 precision at first ("to be safe", or "because it does not cost anything") and then finally decides to round the result to 0.1 precision because that is what he really needs.
