What are the required steps to convert base 10 decimal system
number 22 491 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;
- 22 491 ÷ 2 = 11 245 + 1;
- 11 245 ÷ 2 = 5 622 + 1;
- 5 622 ÷ 2 = 2 811 + 0;
- 2 811 ÷ 2 = 1 405 + 1;
- 1 405 ÷ 2 = 702 + 1;
- 702 ÷ 2 = 351 + 0;
- 351 ÷ 2 = 175 + 1;
- 175 ÷ 2 = 87 + 1;
- 87 ÷ 2 = 43 + 1;
- 43 ÷ 2 = 21 + 1;
- 21 ÷ 2 = 10 + 1;
- 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.
22 491(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
22 491 (base 10) = 101 0111 1101 1011 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
