What are the required steps to convert base 10 decimal system
number 20 021 877 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;
- 20 021 877 ÷ 2 = 10 010 938 + 1;
- 10 010 938 ÷ 2 = 5 005 469 + 0;
- 5 005 469 ÷ 2 = 2 502 734 + 1;
- 2 502 734 ÷ 2 = 1 251 367 + 0;
- 1 251 367 ÷ 2 = 625 683 + 1;
- 625 683 ÷ 2 = 312 841 + 1;
- 312 841 ÷ 2 = 156 420 + 1;
- 156 420 ÷ 2 = 78 210 + 0;
- 78 210 ÷ 2 = 39 105 + 0;
- 39 105 ÷ 2 = 19 552 + 1;
- 19 552 ÷ 2 = 9 776 + 0;
- 9 776 ÷ 2 = 4 888 + 0;
- 4 888 ÷ 2 = 2 444 + 0;
- 2 444 ÷ 2 = 1 222 + 0;
- 1 222 ÷ 2 = 611 + 0;
- 611 ÷ 2 = 305 + 1;
- 305 ÷ 2 = 152 + 1;
- 152 ÷ 2 = 76 + 0;
- 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.
20 021 877(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
20 021 877 (base 10) = 1 0011 0001 1000 0010 0111 0101 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
