Programmer Calculator
Evaluate integer expressions across bases (hex/oct/bin/dec) with bitwise operators. Enter your values, click Calculate, and get the full result with its breakdown — everything is processed on your device, nothing is sent to a server.
All calculations run in your browser. Your data is never sent to our servers.
Example
Example Input
(0xFF & 0x0F) << 2
Example Output
60 (0x3C, 0o74, 0b111100)
How to Use
- 1Fill in each input field with the values you want to compute.
- 2If there are choices (units, mode, operation), pick what you need.
- 3Click the Calculate button (or press Ctrl+Enter).
- 4The main result and its breakdown appear in the Result area. Click Copy to copy it.
About the Programmer Calculator
The Programmer Calculator is built for developers: it evaluates integer expressions mixing bases (e.g. 0xFF, 0o755, 0b1010, 255) with arithmetic and bitwise operators (& | ^ << >> + − × ÷ %). The result is shown at once in decimal, hex, octal, and binary.
It uses BigInt so it is safe for very large integers with no precision loss. There is no eval — a dedicated parser only recognises numbers and operators.
FAQ
Is this Programmer Calculator accurate?
Yes. It uses standard formulas and runs directly in your browser at full JavaScript precision (plus BigInt/decimal.js for large numbers where needed).
Is my data sent to a server?
No. All calculations happen entirely on your device. No values are sent to or stored on our servers.
