Base N

Installation

``(shellscript)
npm i -S @rniv/base-n
`

Getting started

`(javascript)
const {BaseN} = required('@rniv/base-n')
const bs16 = new BaseN('0123456789abcdef')
// n = {{symbols.length}} (base)
`

$3

encode method will return base n string of given number.

Syntax

> encode(n: number): string

`(javascript)
console.log(bs16.encode(100)) // output 64
`

$3

decode method will return decimal value of given base n string

Syntax

> decode(s: string): number

`(javascript)
console.log(bs16.decode('1f')) // output 31
`

$3

add method will return base n string. i.e, sum of given two base n strings

Syntax

> add(s1: string, s2: string): string

`(javascript)
console.log(bs16.add('1f', '1f')) // output 3e
`

$3

subtract method will return base n string. i.e, subtraction of given two base n strings

Note By default subtract will return absolute value

Syntax

> subtract(s1: string, s2: string, abs=true): string
>
> Note: subtract method "abs" parameter defaults to true

`(javascript)
console.log(bs16.subtract('1ff', '10')) // output 1ef
console.log(bs16.subtract('10', '1ff')) // output 1ef
console.log(bs16.subtract('10', '1ff', false)) // output -1ef
`

$3

compare method will return 1|0|-1

Syntax

>compare(s1: string, s2:string): number

Example:
> s1 > s2 => 1
>
> s1 = s2 => 0
>
> s1 < s2 => -1

`(javascript)
console.log(bs16.compare('1ff', '10')) // output 1
console.log(bs16.compare('1ff', '1ff')) // output 0
console.log(bs16.compare('1f', '1ff')) // -1
