Available on crate feature std only.

Extends Float with std-only functionality.

Note that as core_float_math stabilises (see #137578), users of this trait should prepare for its deprecation.

Safety

All items must behave exactly as their standard counterparts.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
