WebThe first part of the response from OCaml, val x : int ref, indicates that x is a variable whose type is int ref. We have a new type constructor here. Much like list and option are type constructors, so is ref. A t ref, for any type t, is a reference to a memory location that is guaranteed to contain a value of type t. WebType bool: Booleans. The boolean values are written true and false . The usual short-circuit conjunction && and disjunction operators are available. Type char: Characters. Characters are written with single quotes, such as 'a', 'b', and 'c'. They are represented as bytes —that is, 8-bit integers— in the ISO 8859-1 “Latin-1” encoding.

WebBoolean values and conditional expressions — OCaml From the Ground Up Boolean values and conditional expressions Equality and comparison operators Conditional expressions … Web4.2 Boolean values The presence of the conditional construct implies the presence of boolean values. The type bool is composed of two values true and false. #true;; - : bool = true #false;; - : bool = false The functions with results of type bool are often called predicates. Many predicates are predefined in Caml. Here are some of them: # ... chen necromorph

WebSep 25, 2024 · In OCaml, a typical fold function looks like this: let rec fold (combine: 'a -> 'b -> 'b) (base: 'b) (l: 'a list) : 'b = begin match l with [] -> base x :: xs -> combine x (fold combine base xs) end For those familiar with OCaml (unlike me), it … WebThe boolean or is written e1 or e2 or e1 e2 . Both constructs are sequential, left-to-right: e2 is evaluated only if needed. Actually, e1 & e2 is equivalent to if e1 then e2 else false , and e1 or e2 is equivalent to if e1 then true else e2. value prefix not : bool -> bool The boolean negation. value string_of_bool : bool -> string WebThe 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 … chenneby soil series
