## Description

Function Calculator is a lightweight, programmable Chrome extension for everyday math, engineering and scientific calculations. It supports basic arithmetic, parentheses, exponentiation, modulo, percentage, square root, mathematical constants (π, e), and engineering functions like sin, cos, tan, log and ln. Convenience features include memory (M+, M-, MR, MC), equation editing (⌫, AC) and an optional vibration toggle.

Beyond standard calculations, Function Calculator offers a JavaScript-like programming layer for custom functions, variables, control flow and loops. Write recursive routines (e.g., factorial, fibonacci), conversion helpers (e.g., celsiusToFahrenheit), and shopping or price lists using variables. Unlimited custom functions plus an easy coding tutorial make it ideal for students, engineers and developers who want repeatable, programmable math inside the browser.
