In the past few days, most of the people were discussed about what is zoned decimal and what are the uses of it. while searching I understood that there are very few articles and tutorials to study about the topic. so letβs discussβ¦ *what are zoned decimals!!!*

In a zone-decimal number has 8 digits (0 and 1). One digit gets one bit. Then 8 digits

get 8 bits. So 8 bits equal to 1 byte. At the final, one zone-decimal number size

equals to 1 byte.

This 8 digits can be divided into two sections as four by four. First four digits show

the sign for zone decimal number. There is 3 sign for zone decimal numbers. Those

are,

β Z β = 1111

β + β = 1100

β - β = 1101

Second four digits show what is the value of the number as a binary number. Those

are,

β 0 β = 0000

β 1 β = 0001

β 2 β = 0010

β 3 β = 0011

β 4 β = 0100

β 5 β = 0101

β 6 β = 0110

β 7 β = 0111

β 8 β = 1000

β 9 β = 1001

Now we can make 10 positive numbers and 10 negative numbers from zone-decimal

numbers using 3 signs and 10 digits(as binary number).

Those are,

β +0 β = 1100 0000

β +1 β = 1100 0001

β +2 β = 1100 0010

β +3 β = 1100 0011

β +4 β = 1100 0100

β +5 β = 1100 0101

β +6 β = 1100 0110

β +7 β = 1100 0111

β +8 β = 1100 1000

β +9 β = 1100 1001

β -0 β = 1101 0000

β -1 β = 1101 0001

β -2 β = 1101 0010

β -3 β = 1101 0011

β -4 β = 1101 0100

β -5 β = 1101 0101

β -6 β = 1101 0110

β -7 β = 1101 0111

β -8 β = 1101 1000

β -9 β = 1101 1001

nice explanation malliβ¦ I think this will help for your batch mates a lot.
