How to convert the base ten number 163 573 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;
- 163 573 ÷ 2 = 81 786 + 1;
- 81 786 ÷ 2 = 40 893 + 0;
- 40 893 ÷ 2 = 20 446 + 1;
- 20 446 ÷ 2 = 10 223 + 0;
- 10 223 ÷ 2 = 5 111 + 1;
- 5 111 ÷ 2 = 2 555 + 1;
- 2 555 ÷ 2 = 1 277 + 1;
- 1 277 ÷ 2 = 638 + 1;
- 638 ÷ 2 = 319 + 0;
- 319 ÷ 2 = 159 + 1;
- 159 ÷ 2 = 79 + 1;
- 79 ÷ 2 = 39 + 1;
- 39 ÷ 2 = 19 + 1;
- 19 ÷ 2 = 9 + 1;
- 9 ÷ 2 = 4 + 1;
- 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.
Number 163 573(10), a positive integer number (with no sign),
converted from decimal system (from base 10)
and written as an unsigned binary (in base 2):
163 573(10) = 10 0111 1110 1111 0101(2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
