In section 3.2.2 of the online Racket documentation a number of the signatures of the functions end with "+", e.g.,:
(max x ...+) → real? Most signatures do not have the +, including those that take an arbitrary number of arguments, e.g.,: (+ z ...) → number? Do the plus signs mean anything, or are they just typos? (The reason I was looking is to see if there is a version of equal? that takes a tolerance, like check-=? from rackunit. What is the preferred way to check equality for inexact numbers?) Thanks!
