What are the required steps to convert base 10 decimal system
number 12 345 179 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;
- 12 345 179 ÷ 2 = 6 172 589 + 1;
- 6 172 589 ÷ 2 = 3 086 294 + 1;
- 3 086 294 ÷ 2 = 1 543 147 + 0;
- 1 543 147 ÷ 2 = 771 573 + 1;
- 771 573 ÷ 2 = 385 786 + 1;
- 385 786 ÷ 2 = 192 893 + 0;
- 192 893 ÷ 2 = 96 446 + 1;
- 96 446 ÷ 2 = 48 223 + 0;
- 48 223 ÷ 2 = 24 111 + 1;
- 24 111 ÷ 2 = 12 055 + 1;
- 12 055 ÷ 2 = 6 027 + 1;
- 6 027 ÷ 2 = 3 013 + 1;
- 3 013 ÷ 2 = 1 506 + 1;
- 1 506 ÷ 2 = 753 + 0;
- 753 ÷ 2 = 376 + 1;
- 376 ÷ 2 = 188 + 0;
- 188 ÷ 2 = 94 + 0;
- 94 ÷ 2 = 47 + 0;
- 47 ÷ 2 = 23 + 1;
- 23 ÷ 2 = 11 + 1;
- 11 ÷ 2 = 5 + 1;
- 5 ÷ 2 = 2 + 1;
- 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.
12 345 179(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
12 345 179 (base 10) = 1011 1100 0101 1111 0101 1011 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
