compare :: a -> a -> Ordering
LT if first parameter is less then second parameter,
EQ if first parameter is equal second parameter, and
GT if first parameter is greater then second parameter
(<) :: a -> a -> Bool infix 4, true if first parameter is less than second parameter otherwise false
(<=) :: a -> a -> Bool infix 4, true if first parameter is equal or less than second parameter otherwise false
(>) :: a -> a -> Bool infix 4, true if first parameter is greater than second parameter otherwise false
(>=) :: a -> a -> Bool infix 4, true if first parameter is equal or greater than second parameter otherwise false
max :: a -> a -> a the greater or equal value of both parameters
min :: a -> a -> a the smaller or equal value of both parameters
