Of course, an "exact decimal number" is not a contradiction in terms. 2.5 is exactly 2.5. or course, _some_ decimal numbers are not storable precisely in the _default_ internal binary format usually used for floats, but that doesn't make the noption nonsensical. But I'll second the suggestion that you use "bc" to do the work, possibly/probably controlled from a shell script.
