DigitArray

The DigitArray library is designed to encode and decode numbers in arbirtary bases.

Example

var decimalValue = new DigitArray(10, [1, 3, 3, 7]);
 
var binaryValue = decimalValue.toBase(2);
 
var hexValue = decimalValue.toBase(16);
 
var encodedDecimalValue = decimalValue.encode('0123456789');
// "1337"
 
var encodedBinaryValue = binaryValue.encode('01');
// "10100111001"
 
var encodedHexValue = hexValue.encode('0123456789abcdef');
// "539"
 
DigitArray.decode(encodedDecimalValue, 10, '0123456789').toNumber();
// 1337
 
DigitArray.decode(encodedBinaryValue, 2, '01').toNumber();
// 1337
 
DigitArray.decode(encodedHexValue, 16, '0123456789abcdef').toNumber();
// 1337
