fixed-point refers to two almost completely unrelated concepts:

- Fixed-point arithmetic, a pragmatic (sometimes even hacky) implementation of approximate real numbers, mostly relevant as an optimisation of numerical performance in memory-constrained applications.
- Fixpoint combinators and the fixpoints of functions which they find. These are of high theoretical interest, considered very elegant, but have rather fewer real-world applications and are often arguably better replaced with more mundane loop constructs if
*performance*is a concern.

I'd suggest splitting this tag in two unambiguous ones: ~~[fixed-precision] for fixed-point arithmetic~~ and fixpoints for fixed-point combinators.

and friends. Do you think that would be worth the trouble?
