This is easy to do (e.g. divide by the appropriate power of 10, use floor,
multiply the power of 10), but you are going about it in the wrong way.

See the "xaxs"  component of the ?par  argument list for the right way.

"Men by nature long to get on to the ultimate truths, and will often be
impatient with elementary studies or fight shy of them. If it were possible
to reach the ultimate truths without the elementary studies usually prefixed
to them, these would not be preparatory studies but superfluous diversions."

-- Maimonides (1135-1204)
