Frequently Asked Questions

What's the difference between the basic and scientific calculator?

The basic calculator includes fundamental arithmetic operations, percentages, and simple functions like square root. The scientific calculator adds advanced functions including trigonometry, logarithms, exponents, and constants.

Can I use this calculator for complex numbers?

Our current calculator focuses on real number operations. For complex number calculations, you would need specialized complex number functions which are not currently supported.

How do I input trigonometric functions?

Click the sin, cos, or tan buttons, then enter the value in parentheses. For example, to calculate sine of 30 degrees (converted to radians), you would enter: sin(30*Ï€/180).

Is there a way to save my calculations?

The calculator maintains a session history of your calculations, but this history is cleared when you close the browser tab. For permanent saving, you would need to manually record your results.

Can I use keyboard shortcuts with the calculator?

Yes, you can type directly into the display field using your keyboard. Most standard calculator keys are supported, including numbers, operators, and parentheses.

How accurate are the calculations?

Our calculator uses JavaScript's built-in mathematical functions, which provide high precision suitable for most scientific and engineering applications. However, like all digital calculators, there may be minor rounding errors in some cases.
