title: TypeScript Type Definitions for BigNumber
body: <p>I'm trying to use <a href="https://github.com/MikeMcl/bignumber.js" rel="nofollow noreferrer">BigNumber</a> version 4.0.2 in a TypeScript program. I've created a stripped down example of a simple Node.js program written in TypeScript that uses BigNumber for this issue
  <a href="https://github.com/naddison36/node-imports" rel="nofollow noreferrer">https://github.com/naddison36/node-imports</a></p>
  
  <p>I'm really struggling to get TypeScript 2.3.4 to pull in the type definitions for BigNumber. Does anyone know how to do this? Here's what I've tried so far <a href="https://github.com/naddison36/node-imports#attempts-to-get-the-bignumber-type-definitions-to-work" rel="nofollow noreferrer">https://github.com/naddison36/node-imports#attempts-to-get-the-bignumber-type-definitions-to-work</a></p>
  
  <p>Ideally I'd like to simply run <code>npm install bignumber.js --save</code>, <code>npm install @types/bignumber.js --save</code>, use ES6 imports like <code>import BigNumber from 'bignumber.js'</code> and have TypeScript just work.</p>
  
  <p>Any help would be appreciated</p>
