What are the required steps to convert base 10 decimal system
number 4 900 127 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;
- 4 900 127 ÷ 2 = 2 450 063 + 1;
- 2 450 063 ÷ 2 = 1 225 031 + 1;
- 1 225 031 ÷ 2 = 612 515 + 1;
- 612 515 ÷ 2 = 306 257 + 1;
- 306 257 ÷ 2 = 153 128 + 1;
- 153 128 ÷ 2 = 76 564 + 0;
- 76 564 ÷ 2 = 38 282 + 0;
- 38 282 ÷ 2 = 19 141 + 0;
- 19 141 ÷ 2 = 9 570 + 1;
- 9 570 ÷ 2 = 4 785 + 0;
- 4 785 ÷ 2 = 2 392 + 1;
- 2 392 ÷ 2 = 1 196 + 0;
- 1 196 ÷ 2 = 598 + 0;
- 598 ÷ 2 = 299 + 0;
- 299 ÷ 2 = 149 + 1;
- 149 ÷ 2 = 74 + 1;
- 74 ÷ 2 = 37 + 0;
- 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.
4 900 127(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
4 900 127 (base 10) = 100 1010 1100 0101 0001 1111 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
