1. Divide the number repeatedly by 2:
Keep track of each remainder.
Stop when you get a quotient that is equal to zero.
- division = quotient + remainder;
- 5 522 097 ÷ 2 = 2 761 048 + 1;
- 2 761 048 ÷ 2 = 1 380 524 + 0;
- 1 380 524 ÷ 2 = 690 262 + 0;
- 690 262 ÷ 2 = 345 131 + 0;
- 345 131 ÷ 2 = 172 565 + 1;
- 172 565 ÷ 2 = 86 282 + 1;
- 86 282 ÷ 2 = 43 141 + 0;
- 43 141 ÷ 2 = 21 570 + 1;
- 21 570 ÷ 2 = 10 785 + 0;
- 10 785 ÷ 2 = 5 392 + 1;
- 5 392 ÷ 2 = 2 696 + 0;
- 2 696 ÷ 2 = 1 348 + 0;
- 1 348 ÷ 2 = 674 + 0;
- 674 ÷ 2 = 337 + 0;
- 337 ÷ 2 = 168 + 1;
- 168 ÷ 2 = 84 + 0;
- 84 ÷ 2 = 42 + 0;
- 42 ÷ 2 = 21 + 0;
- 21 ÷ 2 = 10 + 1;
- 10 ÷ 2 = 5 + 0;
- 5 ÷ 2 = 2 + 1;
- 2 ÷ 2 = 1 + 0;
- 1 ÷ 2 = 0 + 1;
2. Construct the base 2 representation of the positive number:
Take all the remainders starting from the bottom of the list constructed above.
5 522 097(10) = 101 0100 0100 0010 1011 0001(2)
3. Determine the signed binary number bit length:
The base 2 number's actual length, in bits: 23.
- A signed binary's bit length must be equal to a power of 2, as of:
- 21 = 2; 22 = 4; 23 = 8; 24 = 16; 25 = 32; 26 = 64; ...
- The first bit (the leftmost) indicates the sign:
- 0 = positive integer number, 1 = negative integer number
The least number that is:
1) a power of 2
2) and is larger than the actual length, 23,
3) so that the first bit (leftmost) could be zero
(we deal with a positive number at this moment)
=== is: 32.
4. Get the positive binary computer representation on 32 bits (4 Bytes):
If needed, add extra 0s in front (to the left) of the base 2 number, up to the required length, 32.
