(define-modify-macro mulf (B) * "SETF NUM to the result of (* NUM B).")
(define-modify-macro divf (B) / "SETF NUM to the result of (/ NUM B).")
(define-modify-macro minf (other) (lambda (current other) (if (< other current) other current)) "Sets the place to new-value if new-value is #'< the current value")
(define-modify-macro maxf (other) (lambda (current other) (if (> other current) other current)) "Sets the place to new-value if new-value is #'> the current value")
