2.1 Equality

procedure

(=? v1 v2)  boolean?

  v1 : any/c
  v2 : any/c
Returns #true, if v1 is equivalent to v2; #false, otherwise.

procedure

(≠? v1 v2)  boolean?

  v1 : any/c
  v2 : any/c
Equivalent to (not (=? v1 v2)).

2.2 Ordering

procedure

(ordered? v)  boolean?

  v : any/c
Returns #true, if v implements the generic ordering interface; #false, otherwise.

procedure

(<? v1 v2)  boolean?

  v1 : ordered?
  v2 : ordered?
Returns #true, if v1 is less than v2; #false, otherwise.

procedure

(>? v1 v2)  boolean?

  v1 : ordered?
  v2 : ordered?
Returns #true, if v1 is greater than v2; #false, otherwise.
