About Scientific Calculator

A scientific calculator that opens as a popup from your toolbar — or press Alt+S. Unlike most calculators, the entire expression stays visible and editable before you evaluate it. Type or tap to build something like sin(45) + sqrt(2) ^ 2, fix typos anywhere in the line, then press Enter or = to commit. The result is automatically copied to your clipboard. Features • Full-expression editing — correct any part of the calculation before you evaluate • Live preview of the result as you type • Scientific functions: sin, cos, tan and their inverses, ln, log, log2, sqrt, cbrt, exp, abs, floor, ceil, round, min, max, pow • Constants: π, e • Factorial (integers and Gamma for fractions), powers, modulo, parentheses, scientific notation • DEG / RAD toggle • Keyboard shortcuts: Enter to evaluate, Ctrl+Backspace to clear, Alt+S to open • Result auto-copied to clipboard on every evaluation • Answer memory — reuse your last result with the Ans button Any feature requests or bug reports, please reach out! Thank you!
