What are the required steps to convert base 10 decimal system
number 2 123 485 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;
- 2 123 485 ÷ 2 = 1 061 742 + 1;
- 1 061 742 ÷ 2 = 530 871 + 0;
- 530 871 ÷ 2 = 265 435 + 1;
- 265 435 ÷ 2 = 132 717 + 1;
- 132 717 ÷ 2 = 66 358 + 1;
- 66 358 ÷ 2 = 33 179 + 0;
- 33 179 ÷ 2 = 16 589 + 1;
- 16 589 ÷ 2 = 8 294 + 1;
- 8 294 ÷ 2 = 4 147 + 0;
- 4 147 ÷ 2 = 2 073 + 1;
- 2 073 ÷ 2 = 1 036 + 1;
- 1 036 ÷ 2 = 518 + 0;
- 518 ÷ 2 = 259 + 0;
- 259 ÷ 2 = 129 + 1;
- 129 ÷ 2 = 64 + 1;
- 64 ÷ 2 = 32 + 0;
- 32 ÷ 2 = 16 + 0;
- 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.
2 123 485(10) Base 10 decimal system number converted and written as a base 2 unsigned binary equivalent:
2 123 485 (base 10) = 10 0000 0110 0110 1101 1101 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
