{-| Returns `True` for `+0` and any positive `Integer`. `nonNegative` is more efficient than `./greaterThanEqual +0` or `./greaterThan -1`. -} let nonPositive = ./nonPositive.dhall let nonNegative : Integer → Bool = λ(n : Integer) → nonPositive (Integer/negate n) let example0 = assert : nonNegative +1 ≡ True let example1 = assert : nonNegative +0 ≡ True let example2 = assert : nonNegative -1 ≡ False in nonNegative
