Trait shared by all reals.

Reals are equipped with functions that are commonly used on reals. The results of those functions only have to be approximately equal to the actual theoretical values.

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.
