What are the required steps to convert base 10 decimal system
number 40 148 231 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;
- 40 148 231 ÷ 2 = 20 074 115 + 1;
- 20 074 115 ÷ 2 = 10 037 057 + 1;
- 10 037 057 ÷ 2 = 5 018 528 + 1;
- 5 018 528 ÷ 2 = 2 509 264 + 0;
- 2 509 264 ÷ 2 = 1 254 632 + 0;
- 1 254 632 ÷ 2 = 627 316 + 0;
- 627 316 ÷ 2 = 313 658 + 0;
- 313 658 ÷ 2 = 156 829 + 0;
- 156 829 ÷ 2 = 78 414 + 1;
- 78 414 ÷ 2 = 39 207 + 0;
- 39 207 ÷ 2 = 19 603 + 1;
- 19 603 ÷ 2 = 9 801 + 1;
- 9 801 ÷ 2 = 4 900 + 1;
- 4 900 ÷ 2 = 2 450 + 0;
- 2 450 ÷ 2 = 1 225 + 0;
- 1 225 ÷ 2 = 612 + 1;
- 612 ÷ 2 = 306 + 0;
- 306 ÷ 2 = 153 + 0;
- 153 ÷ 2 = 76 + 1;
- 76 ÷ 2 = 38 + 0;
- 38 ÷ 2 = 19 + 0;
- 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.
40 148 231(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
40 148 231 (base 10) = 10 0110 0100 1001 1101 0000 0111 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
