Boolean values.
Since 4.08
Booleans
type t = bool =
| false
| true
The type of booleans (truth values).
The constructors false and true are included here so that they have
paths, but they are not intended to be used in user-defined data types.
val not : bool -> bool
not b is the boolean negation of b .
val (&&) : bool -> bool -> bool
e0 && e1 is the lazy boolean conjunction of expressions e0 and e1 . If
e0 evaluates to false , e1 is not evaluated. Right-associative operator
at precedence level 3/11.
val (||) : bool -> bool -> bool
e0 || e1 is the lazy boolean disjunction of expressions e0 and e1 . If
e0 evaluates to true , e1 is not evaluated. Right-associative operator
at precedence level 2/11.
Predicates and comparisons
val equal : bool -> bool -> bool
equal b0 b1 is true if and only if b0 and b1 are both true or both
false .
val compare : bool -> bool -> int
compare b0 b1 is a total order on boolean values. false is smaller
than true .
Converting
val to_int : bool -> int
to_int b is 0 if b is false and 1 if b is true .
val to_float : bool -> float
to_float b is 0. if b is false and 1. if b is true .
val to_string : bool -> string
to_string b is "true" if b is true and "false" if b is false .
