Integer

Rescript

• 32-bits, truncated when necessary
• Much smaller range than JS numbers. Use float if bigger number needed.
• Js.Int Doc
• Js.Int Source

let n = 1_234_456
let m = n + n * n - n / n
let x = mod(10, 3) // remainder

Js.log(Js.Int.max) //  2147483647
Js.log(Js.Int.min) // -2147483648
Js.log(Js.Int.toFloat(10))

OCaml

• 31-bits or 63-bits depends on platform. Why?
• Int module

let n = 1_234_456 ;;
let m = n + n * n - n / n ;;
let x = 10 mod 3 ;; 
let x = (mod) 10 3 ;;

Int.add 1 1 (* 2 *)
Int.of_float 10.2 (* 10 *)
