27 Booleans
28 type t = bool =
29 | false
30 | true
31
32
33 The type of booleans (truth values).
34
35 The constructors false and true are included here so that they have
36 paths, but they are not intended to be used in user-defined data types.

40 val not : bool -> bool
41
42
43 not b is the boolean negation of b .

47 val (&&) : bool -> bool -> bool
48
49
50 e0 && e1 is the lazy boolean conjunction of expressions e0 and e1 . If
51 e0 evaluates to false , e1 is not evaluated. Right-associative operator
52 at precedence level 3/11.

59 e0 || e1 is the lazy boolean disjunction of expressions e0 and e1 . If
60 e0 evaluates to true , e1 is not evaluated. Right-associative operator
61 at precedence level 2/11.

74 val compare : bool -> bool -> int
75
76
77 compare b0 b1 is a total order on boolean values. false is smaller
78 than true .
