Converting a int to a BCD byte array

Question

I want to convert an int to a byte[2] array using BCD. The int in question will come from DateTime representing the Year and must be converted to two bytes. Is there any pre-made function that does this or can you give me a simple way of doing this? example: int year = 2010 would output: byte[2]{0x20, 0x10}; JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

static byte[] Year2Bcd(int year) { if (year < 0 || year > 9999) throw new ArgumentException(); int bcd = 0; for (int digit = 0; digit < 4; ++digit) { int nibble = year % 10; bcd |= nibble << (digit * 4); year /= 10; } return new byte[] { (byte)((bcd >> 8) & 0xff), (byte)(bcd & 0xff) }; } Beware that you asked for a big-endian result, that's a bit unusual.
