How to convert the base ten number 13 678 to base two:
- 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.
To convert a base ten unsigned number (written in decimal system) to base two (written in binary), follow the steps below.
- Divide the number repeatedly by 2: keep track of each remainder.
- Stop when you get a quotient that is equal to zero.
- Construct the base 2 representation of the positive number: take all the remainders starting from the bottom of the list constructed above.
- Below you can see the conversion process to base two and the related calculations.
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;
- 13 678 ÷ 2 = 6 839 + 0;
- 6 839 ÷ 2 = 3 419 + 1;
- 3 419 ÷ 2 = 1 709 + 1;
- 1 709 ÷ 2 = 854 + 1;
- 854 ÷ 2 = 427 + 0;
- 427 ÷ 2 = 213 + 1;
- 213 ÷ 2 = 106 + 1;
- 106 ÷ 2 = 53 + 0;
- 53 ÷ 2 = 26 + 1;
- 26 ÷ 2 = 13 + 0;
- 13 ÷ 2 = 6 + 1;
- 6 ÷ 2 = 3 + 0;
- 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.
Number 13 678(10), a positive integer number (with no sign),
converted from decimal system (from base 10)
and written as an unsigned binary (in base 2):
13 678 (base 10) = 11 0101 0110 1110 (base 2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
