Advanced Calculator

The calculator covers basic arithmetic (addition, subtraction, multiplication, division), as well as scientific functions including trigonometry (sine, cosine, tangent and their inverses), logarithms (log and ln), exponentials, square roots, and factorials. You can switch between basic and scientific modes depending on what you need.

Yes. The calculator keeps a history of your calculations within the current session. You can scroll through previous results, click on a past result to reuse it, and pick up where you left off. The history is cleared when you close or refresh the page.

Yes, the calculator is fully responsive and works on smartphones, tablets, and desktop computers. The layout adapts to your screen size, and all buttons are sized for comfortable use on touch screens.

Yes. For very large or very small numbers, results are automatically displayed in scientific notation (e.g., 1.5e+10) to keep the output readable. You can also enter values in scientific notation directly in expressions.

Basic mode shows the standard arithmetic buttons (digits, +, −, ×, ÷, and a few extras). Scientific mode expands the interface to include trigonometric functions, logarithms, constants like π and e, parentheses for grouping, and exponentiation. Use scientific mode for anything beyond everyday arithmetic.
