All your base

Convert from one base to another

Installation

npm install all-your-base

Install as command line tool

npm link from your local repo's root. The executable is named ayb.

Usage

Use this in your own scripts and/or as a quick stand-alone command-line tool.

From a script

var ayb = require('all-your-base');

// convert 'abcdef', from base-16 to base-2
ayb.parseInt('abcdef', 16, 2)

// Or directly call the conversion methods
ayb.decToBin(22);
ayb.hexToDec('10000');

From command line

First, type npm link from your local repo's root directory. The executable is named ayb. Name a method & space separate your arguments.

$ ayb parseInt 65536 10 16
10000
$ ayb hexToDec 10000
65536

List of all operations

Here's an exhaustive list for your reference.

parseInt

The native parseInt method will let you convert another base to base-10. But the one provided in this module will let you convert to another base. It's merely a wrapper for the other conversion methods.

• ayb.parseInt(value, fromBase, toBase)
  • value, String. The value in the base you want to convert.
  • fromBase, Number. Specify the base you are converting from.
    • If you are using a script & pass in undefined, then it is assumed you are converting from base-10
  • toBase, Number.Specify the base you are converting to.
    • If you don't pass in anything, then it is assumed you are converting from base-10.

For the following methods, pass in a numerical as a string.

From binary

• binToDec
• binToHex
• binToOct

From octal

• octToDec
• octToBin
• octToHex

From decimal

• decToBin
• decToHex
• decToOct

From hexadecimal

• hexToDec
• hexToBin
• hexToOct

The pattern: [old]To[New]
[old] is the first three letters of the base you are converting from.
[New] is the first three letters of the base to convert to.

Notice, the function name is lowerCamelCased.
