What are the required steps to convert base 10 decimal system
number 85 020 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;
- 85 020 ÷ 2 = 42 510 + 0;
- 42 510 ÷ 2 = 21 255 + 0;
- 21 255 ÷ 2 = 10 627 + 1;
- 10 627 ÷ 2 = 5 313 + 1;
- 5 313 ÷ 2 = 2 656 + 1;
- 2 656 ÷ 2 = 1 328 + 0;
- 1 328 ÷ 2 = 664 + 0;
- 664 ÷ 2 = 332 + 0;
- 332 ÷ 2 = 166 + 0;
- 166 ÷ 2 = 83 + 0;
- 83 ÷ 2 = 41 + 1;
- 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.
85 020(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
85 020 (base 10) = 1 0100 1100 0001 1100 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
