Pure functions. When you use functional operations such as Nest and Map, you always have to specify a function to apply. In all the examples above, we have used the "name" of ...

Mathematica supports zeta and polylogarithm functions of a complex variable in full generality, performing efficient arbitrary-precision evaluation and implementing extensive ...

Simplify[expr] performs a sequence of algebraic and other transformations on expr, and returns the simplest form it finds. Simplify[expr, assum] does simplification using ...

Mathematica is built to handle arbitrarily large computations—limited only by computer time and memory—and provides a collection of convenient global safety features to ...

Mathematica can represent bit vectors of arbitrary length as integers, and uses highly optimized algorithms—including several original to Wolfram Research—to perform bitwise ...

With <<, you can read files that contain Mathematica expressions given in input form. Sometimes, however, you may instead need to read files of data in other formats. For ...

Mathematica can efficiently exchange data in all standard numerical formats—allowing convenient symbolic specification of data subsets and data elements.

ExponentStep is an option for NumberForm and related functions that determines in what steps exponents are taken to increase when scientific notation is used.

$ProcessID gives the ID assigned to the Mathematica kernel process by the operating system under which it is run.

$Version is a string that gives the version of the Mathematica kernel you are running.
