ReScript bindings for Big.js library

Package Exports

  • rescript-big
  • rescript-big/lib/Big.bs.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (rescript-big) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

rescript-big

Actions Status

In this version only these methods are supported: toFixed, plus, minus, div, times, valueOf, round, eq, gt, gte, lt and lte

It also have some converters and shortcuts for converting an existing value or making a Big value, such as: fromFloator toFloat.

It's accompanied with an Operators module which override some operators like +., *., /. and -.

Run the following command:

$ yarn add rescript-big

Then add rescript-big to your bsconfig.json's dependencies:

 {
   "bs-dependencies": [
+    "rescript-big"
   ]
 }

💻 Usage

open! Big.Operators

let a = 201.57512->Big.fromFloat
Js.log(a->Big.toFixed(2)) // 201.58

// Compiler error: 1. is a float, wanted Big.t
let c = a *. 1.

// OK
let b = 1.->Big.fromFloat
let c = a *. b
Js.log(Big.valueOf(c)) // 201.57512
