About Scientific Calculator
A serious scientific calculator without hunting for the classic TI-30 in your desk drawer. Filenify's scientific calculator gives you trig (sin, cos, tan and inverses, in degrees or radians), logs (log, ln), exponents (e^x, x^y), factorials, constants (π, e), and full parenthesis nesting — with a persistent history sidebar you can scroll back through and reuse. Keyboard support lets you type calculations naturally: numbers, operators, parentheses, and Enter all work as expected. History persists between sessions on the same device via localStorage.
How Scientific Calculator works
- 1Type a calculation with the keyboard or click buttons.
- 2Use parentheses to group operations exactly as in math.
- 3Switch between degrees and radians from the mode toggle.
- 4Scroll the history sidebar to reuse or clear earlier calculations.
