Prefer range membership over equivalent bound comparisons

stylewarningautomatic fixmodule

Separate lower-bound and upper-bound comparisons obscure a range membership test. Instead, you SHOULD call .contains() on the corresponding range.

Out-of-range disjunctions over floating-point values are excluded because negating .contains() changes NaN behavior.
