maximumBound :: (Foldable f, Ord a) => a -> f a -> a
safe Safe.Foldable
The largest element of a foldable structure. The result is bounded by the value given as the first argument.
minimumBound :: (Foldable f, Ord a) => a -> f a -> a
safe Safe.Foldable
The smallest element of a foldable structure. The result is bounded by the value given as the first argument.
minimumDef :: (Foldable t, Ord a) => a -> t a -> a
safe Safe.Foldable
New users are recommended to use minimumBound or maximumBound instead.
