rescript-dinero

A low-code ReScript bindings package for dinero.js v2. (currently in Alpha)

Note that most types that expect a JavaScript integer accept a ReScript float. This is because the int in ReScript is only 32 bits wide, whereas JavaScript integers can be safely represented up to 53 bits. i.e. (2 ** 53) - 1 in JavaScript, vs (2 ** 32) - 1 in ReScript. To ensure you are using a Number without a floating point you can use Int53.fromFloat on a float value (that you do not care about the floating-point component) that is not known at compile-time.

Usage

Int53 (JavaScript Number)

Int53 is the default value type for these dinero bindings, and should work out of the box with the default number calculator. However, if you want to use the ReScript implementation of the calculator, you can use the following:

let int53Dinero = Dinero.Make.createDinero({calculator: Calculator.int53Calculator})

BigInt

Requires @dinero.js/calculator-bigint to be installed. Unless you know you will need the precision of bigint, you may not want to use this as it incurs a runtime cost.

let bigintDinero = Dinero.Make.createDinero({calculator: Calculator.bigintCalculator})

Int32

This is not recommended unless you know ahead of time the values will be constrained to 32bit integers.

let int32Dinero = Dinero.Make.createDinero({calculator: Calculator.int32Calculator})
