1. Divide the number repeatedly by 2:
Keep track of each remainder.
We stop when we get a quotient that is equal to zero.
- division = quotient + remainder;
- 7 092 152 ÷ 2 = 3 546 076 + 0;
- 3 546 076 ÷ 2 = 1 773 038 + 0;
- 1 773 038 ÷ 2 = 886 519 + 0;
- 886 519 ÷ 2 = 443 259 + 1;
- 443 259 ÷ 2 = 221 629 + 1;
- 221 629 ÷ 2 = 110 814 + 1;
- 110 814 ÷ 2 = 55 407 + 0;
- 55 407 ÷ 2 = 27 703 + 1;
- 27 703 ÷ 2 = 13 851 + 1;
- 13 851 ÷ 2 = 6 925 + 1;
- 6 925 ÷ 2 = 3 462 + 1;
- 3 462 ÷ 2 = 1 731 + 0;
- 1 731 ÷ 2 = 865 + 1;
- 865 ÷ 2 = 432 + 1;
- 432 ÷ 2 = 216 + 0;
- 216 ÷ 2 = 108 + 0;
- 108 ÷ 2 = 54 + 0;
- 54 ÷ 2 = 27 + 0;
- 27 ÷ 2 = 13 + 1;
- 13 ÷ 2 = 6 + 1;
- 6 ÷ 2 = 3 + 0;
- 3 ÷ 2 = 1 + 1;
- 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.
7 092 152(10) = 110 1100 0011 0111 1011 1000(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.
Decimal Number 7 092 152(10) converted to signed binary in two's complement representation:
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
