Description |
kA comparison function that returns True if the left hand side is less than the right hand side. The same as < in math.
Integers are compared by value, so (ls 1 2) -> True, but (ls 1 1) -> Nil
Strings are compared by alphabetical position, so (ls "a" "b") -> True, but (ls "a" "A") -> Nil
Lists are compared by length, so (ls '(2) '(1 1)) -> True, but (ls '(1) '(2)) -> Nil |
Example |
(ls 7 3)
Returns Nil.
(ls "Betel" "Betelgeuse")
Returns True.
(ls '(a a b) '(c d e))
Returns True.
(ls "B" "b")
Returns Nil. |
