What are the required steps to convert base 10 decimal system
number 3 628 800 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;
- 3 628 800 ÷ 2 = 1 814 400 + 0;
- 1 814 400 ÷ 2 = 907 200 + 0;
- 907 200 ÷ 2 = 453 600 + 0;
- 453 600 ÷ 2 = 226 800 + 0;
- 226 800 ÷ 2 = 113 400 + 0;
- 113 400 ÷ 2 = 56 700 + 0;
- 56 700 ÷ 2 = 28 350 + 0;
- 28 350 ÷ 2 = 14 175 + 0;
- 14 175 ÷ 2 = 7 087 + 1;
- 7 087 ÷ 2 = 3 543 + 1;
- 3 543 ÷ 2 = 1 771 + 1;
- 1 771 ÷ 2 = 885 + 1;
- 885 ÷ 2 = 442 + 1;
- 442 ÷ 2 = 221 + 0;
- 221 ÷ 2 = 110 + 1;
- 110 ÷ 2 = 55 + 0;
- 55 ÷ 2 = 27 + 1;
- 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.
3 628 800(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
3 628 800 (base 10) = 11 0111 0101 1111 0000 0000 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
