What are the required steps to convert base 10 decimal system
number 42 999 722 to base 2 unsigned binary equivalent?
- A number written in base ten, or a decimal system number, is a number written using the digits 0 through 9. A number written in base two, or a binary system number, is a number written using only the digits 0 and 1.
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;
- 42 999 722 ÷ 2 = 21 499 861 + 0;
- 21 499 861 ÷ 2 = 10 749 930 + 1;
- 10 749 930 ÷ 2 = 5 374 965 + 0;
- 5 374 965 ÷ 2 = 2 687 482 + 1;
- 2 687 482 ÷ 2 = 1 343 741 + 0;
- 1 343 741 ÷ 2 = 671 870 + 1;
- 671 870 ÷ 2 = 335 935 + 0;
- 335 935 ÷ 2 = 167 967 + 1;
- 167 967 ÷ 2 = 83 983 + 1;
- 83 983 ÷ 2 = 41 991 + 1;
- 41 991 ÷ 2 = 20 995 + 1;
- 20 995 ÷ 2 = 10 497 + 1;
- 10 497 ÷ 2 = 5 248 + 1;
- 5 248 ÷ 2 = 2 624 + 0;
- 2 624 ÷ 2 = 1 312 + 0;
- 1 312 ÷ 2 = 656 + 0;
- 656 ÷ 2 = 328 + 0;
- 328 ÷ 2 = 164 + 0;
- 164 ÷ 2 = 82 + 0;
- 82 ÷ 2 = 41 + 0;
- 41 ÷ 2 = 20 + 1;
- 20 ÷ 2 = 10 + 0;
- 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.
42 999 722(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
42 999 722 (base 10) = 10 1001 0000 0001 1111 1010 1010 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
