const newId = id(); // W6hOC2N
const password = id({length: 12, charSet: 'all'}); // f5HK7-s$Q2$#
const _id = id(9); // df9HN5rf3

num( min?: number, max?: number )

Generate random number in specific range.

import { num } from 'rangen';

const newNum = num(); // 864

| param | default value | | :------: | :--------------: | | min (optional) | 0 | | max (optional) | 9999 |

Generate random floating-point number in specific range.

  4, // from
  5, // to
  3, // round to a set number of decimal places,
  true // return string (if you want to keep 00 e.g.)
);
// '4.830'

bool( trueProbability?: number )
