I wonder if you could extend it so that it provides *real world*
flexibility. The kind of flexibility you've described, where you
choose a single break point above which everything rounds up, is
actually not one that I have ever heard of anyone needing.

What many people in the real world *do* need is the ability to round
toward even. That is, 1.5 rounds to 2.0, but 4.5 rounds to 4.0. (It's
much less common to want to round toward odd, but maybe that's
something that ought to provided if round-toward-even is provided,
because "why not?". And for symmetry.)

Sounds like a good idea for someone to do. It is on the midrange wiki so it is public domain to do what you like.
