What are the required steps to convert base 10 decimal system
number 18 454 738 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;
- 18 454 738 ÷ 2 = 9 227 369 + 0;
- 9 227 369 ÷ 2 = 4 613 684 + 1;
- 4 613 684 ÷ 2 = 2 306 842 + 0;
- 2 306 842 ÷ 2 = 1 153 421 + 0;
- 1 153 421 ÷ 2 = 576 710 + 1;
- 576 710 ÷ 2 = 288 355 + 0;
- 288 355 ÷ 2 = 144 177 + 1;
- 144 177 ÷ 2 = 72 088 + 1;
- 72 088 ÷ 2 = 36 044 + 0;
- 36 044 ÷ 2 = 18 022 + 0;
- 18 022 ÷ 2 = 9 011 + 0;
- 9 011 ÷ 2 = 4 505 + 1;
- 4 505 ÷ 2 = 2 252 + 1;
- 2 252 ÷ 2 = 1 126 + 0;
- 1 126 ÷ 2 = 563 + 0;
- 563 ÷ 2 = 281 + 1;
- 281 ÷ 2 = 140 + 1;
- 140 ÷ 2 = 70 + 0;
- 70 ÷ 2 = 35 + 0;
- 35 ÷ 2 = 17 + 1;
- 17 ÷ 2 = 8 + 1;
- 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.
18 454 738(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
18 454 738 (base 10) = 1 0001 1001 1001 1000 1101 0010 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
