# 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
```javascript
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.
```bash
$ ayb parseInt 65536 10 16
10000
$ ayb hexToDec 10000
65536
```

### Supported bases
| base/radix | name | module's abbr. |
|:-----------|:------------|:---------------|
| base 2 | binary | `bin` |
| base 8 | octal | `oct` |
| base 10 | decimal | `dec` |
| base 16 | hexadecimal | `hex` |
### 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.
