What are the required steps to convert base 10 decimal system
number 4 450 221 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;
- 4 450 221 ÷ 2 = 2 225 110 + 1;
- 2 225 110 ÷ 2 = 1 112 555 + 0;
- 1 112 555 ÷ 2 = 556 277 + 1;
- 556 277 ÷ 2 = 278 138 + 1;
- 278 138 ÷ 2 = 139 069 + 0;
- 139 069 ÷ 2 = 69 534 + 1;
- 69 534 ÷ 2 = 34 767 + 0;
- 34 767 ÷ 2 = 17 383 + 1;
- 17 383 ÷ 2 = 8 691 + 1;
- 8 691 ÷ 2 = 4 345 + 1;
- 4 345 ÷ 2 = 2 172 + 1;
- 2 172 ÷ 2 = 1 086 + 0;
- 1 086 ÷ 2 = 543 + 0;
- 543 ÷ 2 = 271 + 1;
- 271 ÷ 2 = 135 + 1;
- 135 ÷ 2 = 67 + 1;
- 67 ÷ 2 = 33 + 1;
- 33 ÷ 2 = 16 + 1;
- 16 ÷ 2 = 8 + 0;
- 8 ÷ 2 = 4 + 0;
- 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.
4 450 221(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
4 450 221 (base 10) = 100 0011 1110 0111 1010 1101 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
