Expand description

Types that can represent real numbers.

Provides values and operations that generally apply to real numbers. As such, this trait is implemented by types using floating-point representations, but this trait is a general numeric trait and can be implemented by other numeric types as well.

Some members of this trait depend on the standard library and the std feature.

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.
