BCD
Introduction
BCD code (Binary-Coded Decimal) is also known as binary-coded decimal number or binary-decimal code.
This coding method utilizes four bits to store a decimal digit, enabling quick conversion between binary and decimal.
Usage
String strForTest = "123456ABCDEF";
// Convert to BCD
byte[] bcd = BCD.strToBcd(strForTest);
// Decode BCD
String str = BCD.bcdToStr(bcd);
