Frequently Asked Questions

What functions does the Scientific Calculator support?

The Scientific Calculator supports trigonometric functions (sin, cos, tan), logarithmic functions (log, ln), square root, power, factorial, absolute value, and constants π and e. You can switch between DEG and RAD modes for angle calculations.

What functions does the scientific calculator support?

It supports trigonometric functions (sin, cos, tan and their inverses), logarithmic functions (log, ln), exponential (e^x), power (x^y), square root, factorial, percentage, and parentheses for grouping expressions. Constants π and e are also available.

Can I use keyboard input?

Yes. You can type numbers and operators directly using your keyboard. Basic operators (+ - * /) and numbers work as expected. Additionally, keyboard shortcuts are available for quick calculations.

Does it support calculation history?

Yes. The calculator maintains a history of your previous calculations, allowing you to review and reference past results without losing your current work. All calculations run locally in your browser.

How accurate is the calculator?

The calculator uses JavaScript's built-in Math functions which provide double-precision floating-point accuracy (approximately 15-17 significant digits). For most practical purposes, this level of precision is more than sufficient.
