That's fine. I'm not particularly attached to that phrasing.

The one thing I would push for is to add a comma to "... decimal is preferred in accounting applications which have strict equality invariants."

... since, as far as I can tell, "which have strict equality invariants" is supposed to be a parenthetical statement explaining why accounting applications prefer to use decimal arithmetic, rather than a constraints on the preference for decimal arithmetic to only those accounting applications that have "strict equality invariants".
