What are the required steps to convert base 10 decimal system
number 4 112 018 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;
- 4 112 018 ÷ 2 = 2 056 009 + 0;
- 2 056 009 ÷ 2 = 1 028 004 + 1;
- 1 028 004 ÷ 2 = 514 002 + 0;
- 514 002 ÷ 2 = 257 001 + 0;
- 257 001 ÷ 2 = 128 500 + 1;
- 128 500 ÷ 2 = 64 250 + 0;
- 64 250 ÷ 2 = 32 125 + 0;
- 32 125 ÷ 2 = 16 062 + 1;
- 16 062 ÷ 2 = 8 031 + 0;
- 8 031 ÷ 2 = 4 015 + 1;
- 4 015 ÷ 2 = 2 007 + 1;
- 2 007 ÷ 2 = 1 003 + 1;
- 1 003 ÷ 2 = 501 + 1;
- 501 ÷ 2 = 250 + 1;
- 250 ÷ 2 = 125 + 0;
- 125 ÷ 2 = 62 + 1;
- 62 ÷ 2 = 31 + 0;
- 31 ÷ 2 = 15 + 1;
- 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.
4 112 018(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
4 112 018 (base 10) = 11 1110 1011 1110 1001 0010 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
