I think, OOo should be more accurate, when the arguments are pure integral
numbers.
As far as I see, in interpr5.cxx the function approxSub is used for subtracting
in all cases. This calls approxEqual, which forces the result to zero, if the
difference is in the last three bits. I am right?
If yes, I suggest to make a case distinction whether the values are pure
integral numbers or not and use a simple minus, when both are pure integral
numbers. As far as I know, IEEE double is accurate up to the last bit in adding,
subtracting and multiplying, in the range of integral numbers. Why should OOo
intentially reduce accuracy?
