zeropad

Zeropad your integers with optional n-length padding.

The default is to give you classic padding behavior where numbers less than 10 are padded with a single zero:
'9' → '09', but you can optionally pad to any length, for example: '9' → '0009'.

Note: Since version 1.1.0 you can also pad negative numbers.

Install

$ npm install --save zeropad

Usage

var zeropad = require('zeropad');

zeropad(5);
// => '05'

zeropad(10, 4);
// => '0010'

zeropad('11', 4);
// => '0011'

zeropad(4, 10);
// => '0000000004');

zeropad(9, 4);
// => '0009');

zeropad(-9, 4);
// => '-0009');
