number-sequence v1.0.2

Incrementer

A simple library that lets you define your own number sequence using arbitrary characters.

Installation

Usage

  let incrementer = require('number-sequence');
  let numsys = "0ABCDEF"; 
  let padChar = "0";
  let length = 2;

  let result = incrementer.increment(numsys, incrementer.padNumberToLength("E",length,padChar); // 0E => 0F
  // OR: 
  result = incrementer.padAndIncrement(numsys, "E", length, padChar); // 0E => 0F
  let scope = incrementer.calculateNumberOfValues(numsys,2); // number of possible values === 7^2 => 49

Examples

1. Number system: "0123456789", length: 2, pad with: "0"

   00 => 01
   99 => 00

2. Number system: "ABCD", length: 2

   AA => AB
   AD => BA

3. Number system: "0123456789ABCDEF", length: 2, pad with: "0"

   0F => 10
   0E => 0F
   99 => 9A

4. Number system: "@%&*", length: 2, pad with "@"

   @@ => @%
   &* => %@
   ** => @@

5. Number system: "ABCD", length: 2

   AA => AB
   AD => BA
