What are the required steps to convert base 10 decimal system
number 1 282 640 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;
- 1 282 640 ÷ 2 = 641 320 + 0;
- 641 320 ÷ 2 = 320 660 + 0;
- 320 660 ÷ 2 = 160 330 + 0;
- 160 330 ÷ 2 = 80 165 + 0;
- 80 165 ÷ 2 = 40 082 + 1;
- 40 082 ÷ 2 = 20 041 + 0;
- 20 041 ÷ 2 = 10 020 + 1;
- 10 020 ÷ 2 = 5 010 + 0;
- 5 010 ÷ 2 = 2 505 + 0;
- 2 505 ÷ 2 = 1 252 + 1;
- 1 252 ÷ 2 = 626 + 0;
- 626 ÷ 2 = 313 + 0;
- 313 ÷ 2 = 156 + 1;
- 156 ÷ 2 = 78 + 0;
- 78 ÷ 2 = 39 + 0;
- 39 ÷ 2 = 19 + 1;
- 19 ÷ 2 = 9 + 1;
- 9 ÷ 2 = 4 + 1;
- 4 ÷ 2 = 2 + 0;
- 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.
1 282 640(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
1 282 640 (base 10) = 1 0011 1001 0010 0101 0000 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
