equal b1 b2 is true if b1 and b2 are the same.

val if_then : (unit -> 'a) -> t -> 'a option

if_then f x is Some (f ()) if x is true and None otherwise.

val if_then_else : (unit -> 'a) -> (unit -> 'a) -> t -> 'a

if_then_else f g x is f () if x is true and g () otherwise.

  • since 3.13
val to_int : t -> int

to_int true = 1, to_int false = 0.

  • since 2.7
val of_int : int -> t

of_int i is the same as i <> 0
