How to convert the base ten number 240 120 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;
- 240 120 ÷ 2 = 120 060 + 0;
- 120 060 ÷ 2 = 60 030 + 0;
- 60 030 ÷ 2 = 30 015 + 0;
- 30 015 ÷ 2 = 15 007 + 1;
- 15 007 ÷ 2 = 7 503 + 1;
- 7 503 ÷ 2 = 3 751 + 1;
- 3 751 ÷ 2 = 1 875 + 1;
- 1 875 ÷ 2 = 937 + 1;
- 937 ÷ 2 = 468 + 1;
- 468 ÷ 2 = 234 + 0;
- 234 ÷ 2 = 117 + 0;
- 117 ÷ 2 = 58 + 1;
- 58 ÷ 2 = 29 + 0;
- 29 ÷ 2 = 14 + 1;
- 14 ÷ 2 = 7 + 0;
- 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.
Number 240 120(10), a positive integer number (with no sign),
converted from decimal system (from base 10)
and written as an unsigned binary (in base 2):
240 120(10) = 11 1010 1001 1111 1000(2)
Spaces were used to group digits: for binary, by 4, for decimal, by 3.
