A collection of packages that implement arithmetic for many number systems in Go.

numbers

Metapackage numbers is a collection of packages that implement arithmetic over many number systems, including dual numbers, quaternions, octonions, and their parabolic and hyperbolic cousins. In each package five types are implemented:

• Int64
• Float64
• Int
• Float
• Rat

Each value is printed in the form "(...)". This is similar to complex128 values.
