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;
- 110 011 110 384 ÷ 2 = 55 005 555 192 + 0;
- 55 005 555 192 ÷ 2 = 27 502 777 596 + 0;
- 27 502 777 596 ÷ 2 = 13 751 388 798 + 0;
- 13 751 388 798 ÷ 2 = 6 875 694 399 + 0;
- 6 875 694 399 ÷ 2 = 3 437 847 199 + 1;
- 3 437 847 199 ÷ 2 = 1 718 923 599 + 1;
- 1 718 923 599 ÷ 2 = 859 461 799 + 1;
- 859 461 799 ÷ 2 = 429 730 899 + 1;
- 429 730 899 ÷ 2 = 214 865 449 + 1;
- 214 865 449 ÷ 2 = 107 432 724 + 1;
- 107 432 724 ÷ 2 = 53 716 362 + 0;
- 53 716 362 ÷ 2 = 26 858 181 + 0;
- 26 858 181 ÷ 2 = 13 429 090 + 1;
- 13 429 090 ÷ 2 = 6 714 545 + 0;
- 6 714 545 ÷ 2 = 3 357 272 + 1;
- 3 357 272 ÷ 2 = 1 678 636 + 0;
- 1 678 636 ÷ 2 = 839 318 + 0;
- 839 318 ÷ 2 = 419 659 + 0;
- 419 659 ÷ 2 = 209 829 + 1;
- 209 829 ÷ 2 = 104 914 + 1;
- 104 914 ÷ 2 = 52 457 + 0;
- 52 457 ÷ 2 = 26 228 + 1;
- 26 228 ÷ 2 = 13 114 + 0;
- 13 114 ÷ 2 = 6 557 + 0;
- 6 557 ÷ 2 = 3 278 + 1;
- 3 278 ÷ 2 = 1 639 + 0;
- 1 639 ÷ 2 = 819 + 1;
- 819 ÷ 2 = 409 + 1;
- 409 ÷ 2 = 204 + 1;
- 204 ÷ 2 = 102 + 0;
- 102 ÷ 2 = 51 + 0;
- 51 ÷ 2 = 25 + 1;
- 25 ÷ 2 = 12 + 1;
- 12 ÷ 2 = 6 + 0;
- 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.
110 011 110 384(10) = 1 1001 1001 1101 0010 1100 0101 0011 1111 0000(2)
3. Determine the signed binary number bit length:
The base 2 number's actual length, in bits: 37.
- 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, 37,
3) so that the first bit (leftmost) could be zero
(we deal with a positive number at this moment)
=== is: 64.
4. Get the positive binary computer representation on 64 bits (8 Bytes):
If needed, add extra 0s in front (to the left) of the base 2 number, up to the required length, 64.
