# Module Batteries.Bool

    module Bool: BatBool

    type t = bool

The type of booleans. Formally, this is defined as `type t = true | false`

    val not : bool -> bool

The boolean negation.

    val (&&) : bool -> bool -> bool

The boolean ``and''. Evaluation is sequential, left-to-right: in `e1 && e2`, `e1` is evaluated first, and if it returns `false`, `e2` is not evaluated at all.

    val (||) : bool -> bool -> bool

The boolean ``or''. Evaluation is sequential, left-to-right: in `e1 || e2`, `e1` is evaluated first, and if it returns `true`, `e2` is not evaluated at all.

    val zero : bool

    val one : bool

    val neg : bool -> bool

    val succ : bool -> bool

    val pred : bool -> bool

    val abs : bool -> bool

    val add : bool -> bool -> bool

    val mul : bool -> bool -> bool

    val sub : bool -> bool -> bool

    val div : t -> t -> t

    val modulo : t -> t -> t

    val pow : t -> t -> t

    val min_num : bool

    val max_num : bool

    val compare : bool -> bool -> int

    val equal : bool -> bool -> bool

    val ord : bool -> bool -> BatOrd.order

    val of_int : int -> bool

anything but `0` is `true`

    val to_int : bool -> int

    val of_string : string -> bool

Convert the given string to a boolean.
Raises `Invalid_argument` if the string is not `"true"`, `"false"`, `"0"`, `"1"`, `"tt"` or `"ff"`.

    val to_string : bool -> string

    val of_float : float -> bool

`0.`, `nan` `+infinity` and `-infiity` are `false`. The other values convert to `true`

    val to_float : bool -> float

    val (+) : t -> t -> t

    val (-) : t -> t -> t

    val ( * ) : t -> t -> t

    val (/) : t -> t -> t

    val ( ** ) : t -> t -> t

    val (--) : t -> t -> t BatEnum.t

    val (---) : t -> t -> t BatEnum.t

    val operations : t BatNumber.numeric

###### Submodules grouping all infix operators

    module Infix: BatNumber.Infix  with type bat__infix_t = t

    module Compare: BatNumber.Compare  with type bat__compare_t = t

###### Boilerplate code

    val print : 'a BatInnerIO.output -> t -> unit
