| Datatype: | Bool |
| Description: | The boolean type Bool is an enumeration. The basic boolean functions are (&&) (and), (||) (or), and not. The name is defined as True to make guarded expressions more readable. |
| Definition: | data Bool = False | True deriving (Read, Show, Eq, Ord, Enum, Bounded) |
| In function types: | Bool : otherwise Bool -> Bool : not Bool -> ShowS -> ShowS : showParen Bool -> ReadS a -> ReadS a : readParen a -> Bool : even, isDenormalized, isIEEE, isInfinite, isNaN, isNegativeZero, odd Bool -> Bool -> Bool : (&&), (||) a -> a -> Bool : (/=), (<), (<=), (==), (>), (>=) [a] -> Bool : null (a -> Bool) -> [a] -> [a] : dropWhile, filter, takeWhile (a -> Bool) -> [a] -> ([a],[a]) : break (a -> Bool) -> [a] -> Bool : all, any [Bool] -> Bool : and, or a -> [a] -> Bool : elem, notElem (a -> Bool) -> (a -> a) -> a -> a : until |
