# hex2dec
[](https://www.npmjs.com/package/hex2dec)

[](https://github.com/donmccurdy/hex2dec/blob/master/LICENSE)
[](https://github.com/donmccurdy/hex2dec/actions?query=workflow%3Abuild)Arbitrary precision decimal↔️hexadecimal converter, from a [blog post](http://www.danvk.org/hex2dec.html) by [Dan Vanderkam](https://github.com/danvk). Supports non-negative integer values.
## Usage
```
npm install --save hex2dec
``````javascript
var converter = require('hex2dec');var dec = converter.hexToDec('0xFA'); // 250
var hex = converter.decToHex('250'); // '0xfa'
var hexString = converter.decToHex('250', { prefix: false }); // 'fa'
```## Why use hex2dec
`(250).toString(16) === 'fa'` and `250 === 0xFA` both work just fine, and will provide enough precision for most uses. For large (>64-bit) numbers, however, precision is lost. This utility provides a higher-precision alternative.
