Advanced Calculator

A full-featured scientific calculator with degrees/radians, trig, logarithms, factorials, memory, and a persistent history panel.

Whether you're working through a math assignment, crunching numbers for an engineering project, or just need something more capable than your basic four-function calculator, this tool's got you covered. It handles everything from straightforward arithmetic to trig functions (sin, cos, tan and their inverses — in degrees or radians), natural and base-10 logarithms, square and cube roots, exponents, factorials, and percent, plus built-in constants like pi and Euler's number. A memory row (MS, MR, M+, MC) and a persistent history panel mean you never lose track of your work. It uses a proper tokenizing parser, so it follows standard order of operations (PEMDAS/BODMAS) and handles unary minus and nested parentheses correctly. All processing happens locally in your browser, so nothing leaves your machine.
