What This Scientific Calculator Can Perform
A lightweight, browser-only scientific calculator with advanced features — no backend required.
The calculator runs completely in your browser and supports a wide range of functions. Basic arithmetic includes addition, subtraction, multiplication and division. It also supports decimals and parentheses (e.g., (5 + 3) * 2.5) and a suite of advanced functions such as exponents and powers (2^5, 3^(1/3)), square root (√9), factorials (5! = 120), logarithms (log10(1000), ln(e)) and trigonometry (sin(30), cos(45), tan(60)). Inverse trig functions (asin, acos, atan) can be typed manually as needed. The calculator also includes constants like π and e, and full keyboard support (numbers, operators, Enter = evaluate, Backspace, etc.).
