The GetTools Scientific Calculator brings two modes together in a single, intuitive interface. Simple mode covers the four basic operations — addition, subtraction, multiplication and division — with percentage and sign toggle, perfect for quick everyday calculations. Scientific mode delivers the full power of a professional calculator directly in your browser, with no installation required.
In scientific mode you get a comprehensive set of mathematical functions: trigonometric functions (sin, cos, tan) and their inverses (sin⁻¹, cos⁻¹, tan⁻¹) in Degree or Radian mode, logarithmic functions (log₁₀, ln, log₂), powers (x², x³, xʸ) and roots (√x, ∛x, ʸ√x), inverse (1/x), absolute value (|x|), factorial (n!), exponential (eˣ), and the mathematical constants π and e.
The tool stands out with a full memory unit (MC, MR, MS, M+, M−) for storing and recalling values at any time, an automatic history of the last 20 calculations with one-click restore, keyboard shortcut support, and a smooth interface that works seamlessly on both mobile and desktop.
