Numeric.Natural.Internal

Description

This module exposes the potentially unsafe operations that are sometimes needed for efficiency: The Natural data constructor and unsafePred.

Synopsis

newtype Natural = Natural {
- runNatural :: Integer
}
class Integral n => Whole n where
- toNatural :: n -> Natural
- unsafePred :: n -> n
