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.
