Programmer Mode

Designed for developers, the Programmer mode allows instant arithmetic and bitwise operations across Hexadecimal, Decimal, Octal, and Binary bases. Tap the base on the screen to switch input modes. The keypad disables invalid characters dynamically.

Inverse Functions

In Scientific mode, click the SHIFT button to unlock inverse trigonometry (arcsin, arccos), cube roots, and exponential powers. The engine handles asymptotes (like tan(90)) gracefully without floating-point artifacts.

Frequently Asked Questions

How does the Programmer Mode work?

Programmer mode allows you to input and calculate values in Hexadecimal, Decimal, Octal, and Binary. It instantly converts your input across all four bases in real-time and supports standard bitwise logic operations (AND, OR, XOR, NOT, Left Shift, Right Shift).

How do I use previous answers?

Click the Ans button to insert your last successful calculation into a new equation. You can also click any result in the Tape History panel to instantly recall it into your current expression.

What is the maximum precision of this calculator?

Powered by the industry-standard Math.js library, expressions are parsed natively and display outputs are safely rounded to 14 significant digits to prevent native binary floating-point anomalies (e.g., the infamous 0.1 + 0.2 error).

Does this tool store my calculation data?

No. All calculations run strictly locally in your browser. Your tape history is volatile and clears upon refresh. No mathematical or personal data is transmitted to our servers.
