hex2dec v1.1.2

hex2dec

Arbitrary precision decimal↔️hexadecimal converter, from a blog post by Dan Vanderkam. Supports non-negative integer values.

Usage

npm install --save hex2dec

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.
