I mean if you can preestimate maximum precision beforehand just use the max. Or use currency so you have a trustable value for calculations.

The idea is that the number you're getting is user input, or import from a file with an unknown number of decimal places (if any), so I could not define lnSignificantdecimals up front. Unless I am missing the true meaning behind your post... if so, please explain.
