What are the required steps to convert base 10 decimal system
number 1 243 525 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;
- 1 243 525 ÷ 2 = 621 762 + 1;
- 621 762 ÷ 2 = 310 881 + 0;
- 310 881 ÷ 2 = 155 440 + 1;
- 155 440 ÷ 2 = 77 720 + 0;
- 77 720 ÷ 2 = 38 860 + 0;
- 38 860 ÷ 2 = 19 430 + 0;
- 19 430 ÷ 2 = 9 715 + 0;
- 9 715 ÷ 2 = 4 857 + 1;
- 4 857 ÷ 2 = 2 428 + 1;
- 2 428 ÷ 2 = 1 214 + 0;
- 1 214 ÷ 2 = 607 + 0;
- 607 ÷ 2 = 303 + 1;
- 303 ÷ 2 = 151 + 1;
- 151 ÷ 2 = 75 + 1;
- 75 ÷ 2 = 37 + 1;
- 37 ÷ 2 = 18 + 1;
- 18 ÷ 2 = 9 + 0;
- 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.
1 243 525(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
1 243 525 (base 10) = 1 0010 1111 1001 1000 0101 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
