Functions Documentation  Name geq Syntax (geq a [b ... bn]) -> True if a >= b >= bn Argument List a: The first expression you want to compare. [b ... bn]: The next expressions you want to compare. Returns boolean: The expressions are compared left to right. If there is any case where the left value is "less" then the right value, `geq' will return Nil. Else it returns True. Category logical operator Description A comparison function that returns true if the left hand side is greated than or equal to the right hand side. The same as >= in math. Integers are compared by value, so (geq 1 1) -> True, but (geq 1 2) -> Nil Strings are compared by alphabetical position, so (geq "a" "A") -> True, but (geq "a" "B") -> Nil Lists are compared by length, so (geq '(1) '(2)) -> True, but (geq '(2) '(1 1)) -> Nil It is advised to play around with this a bit to get a feeling of how things compare Example `(geq 7 3)` Returns True. `(geq "Betel" "Betelgeuse")` Returns Nil. `(geq '(a a b) '(c d e))` Returns Nil. `(geq "B" "b")` Returns True. Comment I am not sure how lists are compared but other than that this is your standard comparison function.
