Add `imprecise_flops` lint Add lint to detect floating point operations that can be computed more accurately at the cost of performance. `cbrt`, `ln_1p` and `exp_m1` library functions call their equivalent cmath implementations which is slower but more accurate so moving checks for these under this new lint. 2020-02-24 05:06:55 +00:00			`#![warn(clippy::imprecise_flops)]`
