// Type definitions for decimal.js >=7.0.0
// Project: https://github.com/MikeMcl/decimal.js
// Definitions by: Michael Mclaughlin <https://github.com/MikeMcl>
// Definitions: https://github.com/MikeMcl/decimal.js
//
// Documentation: http://mikemcl.github.io/decimal.js/
//
// Exports:
//
// class Decimal (default export)
// type Decimal.Constructor
// type Decimal.Instance
// type Decimal.Modulo
// type Decimal.Rounding
// type Decimal.Value
// interface Decimal.Config
//
// Example (alternative syntax commented-out):
//
// import {Decimal} from "decimal.js"
// //import Decimal from "decimal.js"
//
// let r: Decimal.Rounding = Decimal.ROUND_UP;
// let c: Decimal.Configuration = {precision: 4, rounding: r};
// Decimal.set(c);
// let v: Decimal.Value = '12345.6789';
// let d: Decimal = new Decimal(v);
// //let d: Decimal.Instance = new Decimal(v);
//
// The use of compiler option `--strictNullChecks` is recommended.
