# Elementary Functions

Using the latest platform-optimized code, the Wolfram Language not only delivers high-efficiency machine-precision evaluation of elementary functions, but alsousing a number of original algorithmsprovides the world's fastest arbitrary-precision evaluation. A sophisticated web of symbolic functions and transformations allows the Wolfram Language to perform exact numerical and algebraic operations on elementary functionseffortlessly obtaining results that in the past would have been viewed as major mathematical accomplishments.
