![]() Automatic exponential formatting in Debug
Context: See [this comment from the libs team](https://github.com/rust-lang/rfcs/pull/2729#issuecomment-853454204)
---
Makes `"{:?}"` switch to exponential for floats based on magnitude. The libs team suggested exploring this idea in the discussion thread for RFC rust-lang/rfcs#2729. (**note:** this is **not** an implementation of the RFC; it is an implementation of one of the alternatives)
Thresholds chosen were 1e-4 and 1e16. Justification described [here](https://github.com/rust-lang/rfcs/pull/2729#issuecomment-864482954).
**This will require a crater run.**
