What are the required steps to convert base 10 decimal system
number 4 042 541 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;
- 4 042 541 ÷ 2 = 2 021 270 + 1;
- 2 021 270 ÷ 2 = 1 010 635 + 0;
- 1 010 635 ÷ 2 = 505 317 + 1;
- 505 317 ÷ 2 = 252 658 + 1;
- 252 658 ÷ 2 = 126 329 + 0;
- 126 329 ÷ 2 = 63 164 + 1;
- 63 164 ÷ 2 = 31 582 + 0;
- 31 582 ÷ 2 = 15 791 + 0;
- 15 791 ÷ 2 = 7 895 + 1;
- 7 895 ÷ 2 = 3 947 + 1;
- 3 947 ÷ 2 = 1 973 + 1;
- 1 973 ÷ 2 = 986 + 1;
- 986 ÷ 2 = 493 + 0;
- 493 ÷ 2 = 246 + 1;
- 246 ÷ 2 = 123 + 0;
- 123 ÷ 2 = 61 + 1;
- 61 ÷ 2 = 30 + 1;
- 30 ÷ 2 = 15 + 0;
- 15 ÷ 2 = 7 + 1;
- 7 ÷ 2 = 3 + 1;
- 3 ÷ 2 = 1 + 1;
- 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.
4 042 541(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
4 042 541 (base 10) = 11 1101 1010 1111 0010 1101 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
