What are the required steps to convert base 10 decimal system
number 25 000 010 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;
- 25 000 010 ÷ 2 = 12 500 005 + 0;
- 12 500 005 ÷ 2 = 6 250 002 + 1;
- 6 250 002 ÷ 2 = 3 125 001 + 0;
- 3 125 001 ÷ 2 = 1 562 500 + 1;
- 1 562 500 ÷ 2 = 781 250 + 0;
- 781 250 ÷ 2 = 390 625 + 0;
- 390 625 ÷ 2 = 195 312 + 1;
- 195 312 ÷ 2 = 97 656 + 0;
- 97 656 ÷ 2 = 48 828 + 0;
- 48 828 ÷ 2 = 24 414 + 0;
- 24 414 ÷ 2 = 12 207 + 0;
- 12 207 ÷ 2 = 6 103 + 1;
- 6 103 ÷ 2 = 3 051 + 1;
- 3 051 ÷ 2 = 1 525 + 1;
- 1 525 ÷ 2 = 762 + 1;
- 762 ÷ 2 = 381 + 0;
- 381 ÷ 2 = 190 + 1;
- 190 ÷ 2 = 95 + 0;
- 95 ÷ 2 = 47 + 1;
- 47 ÷ 2 = 23 + 1;
- 23 ÷ 2 = 11 + 1;
- 11 ÷ 2 = 5 + 1;
- 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.
25 000 010(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
25 000 010 (base 10) = 1 0111 1101 0111 1000 0100 1010 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
