Formula and calculation method
Read operands in base 2, perform integer arithmetic, and convert the result back to base 2.
Division truncates toward zero and uses arbitrary-precision integers.
How to use binary calculator
- Set First number. The example below uses 1010.
- Set Operation by choosing the option that matches your calculation.
- Set Second number. The example below uses 10.
- Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.

Factors affecting your result
Division truncates toward zero and uses arbitrary-precision integers.
Changing first number changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
Frequently asked questions
How does the binary calculator work?
Read operands in base 2, perform integer arithmetic, and convert the result back to base 2.
What inputs does Binary Calculator need?
Enter first number, operation, second number. Choose values that correspond to the same situation and measurement convention.
How should I interpret the binary calculator result?
Division truncates toward zero and uses arbitrary-precision integers.
Are my binary calculator inputs uploaded?
No. The calculation runs in this browser. Favorites, recent tool names, theme and formatting preferences may be saved locally, but calculation inputs are not sent to a calculation server or stored by this website. Shared links do not include entered values.
