I think you got that wrong, floating is precisely designed for such
comparisons. You can easily compare 1e+1000 with 1e-1000 without running
into problems.

Where you might run into problems is if you *add* (or subtract)
extremely small numbers from extremely big numbers. Or if you divide by
extremely small numbers. Or in general perform operations that mix
numbers of greatly unlike magnitudes.
