Perhaps the OP doesn't really care about this, but FWIW one thing I recall from high school science (or maybe it was middle school), the zeros to the right of the decimal place ARE meaningful, i.e., 1000.000 signifies something different than 1000, namely, a measurement three orders of magnitude more precise. So "chopping off non-meaningful digits" is something you ought to do only for zeros on the left.
