false?
tests whether the provided forms are boolean false
Usage:
(false? form+) (!false? form+) (is-false form)
If all forms evaluate to false (#f), then this function will return #t (true). The first non-false will result in the function returning #f (false).
An Example
(false? (< 3 2) (> 5 10))
This example will return #t (true) because all the equalities result in #f (false).
Like most predicates, this function can also be negated by prepending the !
character. This means that all the provided forms must not be true. This is equivalent to the true? predicate.
(!false? #t (< 5 10))
This example will return #t (true).
