Binary-coded decimal : Binary coded decimalBinary coded decimal (BCD) is a numeral system used in computer memory. In BCD, numbers are represented as decimal digits, and each digit is represented by four bits:
Digit Bits Digit Bits 0 0000 5 0101 1 0001 6 0110 2 0010 7 0111 3 0011 8 1000 4 0100 9 1001To encode a number such as 127, then, one simply encodes each of the decimal digits as above, giving (0001, 0010, 0111). Since most computers store data in eight-bit bytes, there are two common ways of storing four-bit BCD digits in those bytes: either one can simply ignore the extra four bits of each byte, usually filling them with zero bits or one bits (as in EBCDIC); or one can store two digits per byte, called "packed" BCD. Thus the number 127 would be represented as (11110001, While BCD is wasteful (about 1/6 of the available memory is wasted, even in packed BCD), it has a direct correspondence to the ASCII character set if the BCD number is prepended or OR'd with 00110000 (decimal 48), and large numbers can easily be displayed on 7-element displays by splitting up the nybbles and sending each to a different character (the individual characters often have the wiring to display the correct figures). The BIOS in PCs usually keeps the date and time in BCD format, probably for historical reasons. that Louis thought he could abdicate the crown of Holland in favour of

As that abdication left Holland for twelve years under a regency,

against England, since his will was supreme in Holland.
But I ascended the throne without any other conditions except those

Paris, where I was detained against my will; and that, moreover, the
