But the real numbers are an ordered field and a type like `Double` (setting 
aside the special values) IS modeling the real numbers. The fact that it's an 
imperfect *representation* of the type it models, that suffers from 
saturation/overflow, imho does not change its nature. imho we should not think 
of `Double` as having anything to do with algebraic "finite fields" even though 
as a representation it is hopelessly finite.
