newnum

Splits the Rust number API and hierarchy into traits, with a cleaner design than the num crate.

The design of this crate follows these rules:

• the Num trait isn't restricted to primitives, doesn't require representing values such as 0 or 1, and is only restricted to representing abstract numbers meaning no measurement units.

• the Prim, SignedPrim, UnsignedPrim, Int, UInt, SInt, and Float traits are restricted to primitives, but allow non std types to impl them as long as they follow primitive restrictions.

• API traits (Round, Root, Trig...) aren't restricted to Num and are designed for non number support, for example <Angle as Trig>::Output = Ratio.

Development State

the current state of this crate is using it for different projects and modifying the design until it hardens, so until then every version will have breaking changes.
