❓ Frequently Asked Questions

🔢 What number types are supported?

The evaluator supports regular numbers, BigNumbers for high precision, and Fractions for exact rational calculations.

📐 How do I work with angles?

You can switch between radians and degrees in the settings. Use functions like sin(90 deg) or cos(pi rad).

🔧 What does "Predictable" mode do?

Predictable mode ensures deterministic results by disabling random functions and making calculations reproducible.

💾 Is calculation history saved?

Yes, your calculation history is stored locally in your browser and persists between sessions.
