What are the required steps to convert base 10 decimal system
number 42 949 328 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;
- 42 949 328 ÷ 2 = 21 474 664 + 0;
- 21 474 664 ÷ 2 = 10 737 332 + 0;
- 10 737 332 ÷ 2 = 5 368 666 + 0;
- 5 368 666 ÷ 2 = 2 684 333 + 0;
- 2 684 333 ÷ 2 = 1 342 166 + 1;
- 1 342 166 ÷ 2 = 671 083 + 0;
- 671 083 ÷ 2 = 335 541 + 1;
- 335 541 ÷ 2 = 167 770 + 1;
- 167 770 ÷ 2 = 83 885 + 0;
- 83 885 ÷ 2 = 41 942 + 1;
- 41 942 ÷ 2 = 20 971 + 0;
- 20 971 ÷ 2 = 10 485 + 1;
- 10 485 ÷ 2 = 5 242 + 1;
- 5 242 ÷ 2 = 2 621 + 0;
- 2 621 ÷ 2 = 1 310 + 1;
- 1 310 ÷ 2 = 655 + 0;
- 655 ÷ 2 = 327 + 1;
- 327 ÷ 2 = 163 + 1;
- 163 ÷ 2 = 81 + 1;
- 81 ÷ 2 = 40 + 1;
- 40 ÷ 2 = 20 + 0;
- 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.
42 949 328(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
42 949 328 (base 10) = 10 1000 1111 0101 1010 1101 0000 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
