An online scientific calculator is a type of electronic calculator capable of performing both basic online mathematical computations and advanced scientific calculations. It offers conversions between different numeral systems, angle and radian calculations, square root computations, and other advanced online operations. Additionally, it can handle operations involving exponentiation, root extraction, exponents, logarithms, trigonometric functions, statistics, and more. It is also known as a function calculator. A scientific calculator is equipped with all common functions, which are directly accessible on the calculator's faceplate, allowing users to utilize them by clicking directly on the calculator's interface rather than navigating through menus or lists.
