Can someone guide me pls.

[01][5E] is not 360 in packed BCD (or in regular hex, for that matter). Please, elaborate. – Maciej Stachowski Nov 12 '13 at 17:37

sorry. it is 350(dec) to 01x5E – Adarsh Nanu Nov 12 '13 at 17:38

that is not what called packed BCD ? [0000 0001] [0101 1110] – Adarsh Nanu Nov 12 '13 at 17:46

BCD is, as its name suggests, binary-coded decimal - i.e. the four-bit "nibbles" correspond to decimal digits. So, 350 would be [03][50] - possibly a little different if you add the sign and byte order, but you get the idea. – Maciej Stachowski Nov 12 '13 at 17:49

Yes. now I am clear. I mixed my requirement with the concept. let me rephrase, I want to pack 015E into two bytes as [0000 0001] [0101 1110] – Adarsh Nanu Nov 12 '13 at 17:58
