Packed BCD has been in use since at least the 1960s and is implemented in all IBM mainframe hardware since then. Most implementations are big endian, i.e. with the more significant digit in the upper half of each byte, and with the leftmost byte (residing at the lowest memory address) containing the most significant digits of the packed decimal value. The lower nibble of the rightmost byte is usually u… tanger discount couponsWebOct 9, 2012 · It somehow is common to store a value from 0to99 in a byte and using the lower and higher nybble as a decimal value.
