  • TypeLevel
    • TypeLevel.Boolean
    • TypeLevel.Number
      • TypeLevel.Number.Classes

This is type level numbers implemented using type families. Natural numbers use binary encoding. With default context stack numbers up to 2^18-1 could be represented. Signed integer numbers use balanced ternary encoding.

Package is structured as folows:

  • [TypeLevel.Number.Classes] contain generic type families such as Add

  • [TypeLevel.Number.Nat] natural numbers implemented using binary encoding

  • [TypeLevel.Number.Int] signed integers implemented using balanced ternary encoding

  • [TypeLevel.Boolean] type level booleans

So far comparison of numbers, subtraction and multiplication of numbers are supported.
