This section provides an overview of what math is, and why a developer might want to use it. It should also mention any large subjects within math, and link out to the related topics. Since the Documentation for math is new, you may need to create initial versions of those related topics.

Forecasting and time-series analysis may be handled with commonplace functions from the stats package, such as glm() or a large number of specialized packages. The CRAN Task View for time-series analysis provides a detailed listing of key packages by topic with short descriptions.

map = %{} // creates an empty map map = %{:a => 1, :b => 2} // creates a non-empty map list = [] // creates an empty list list = [{:a, 1}, {:b, 2}] // creates a non-empty keyword list Elixir provides two associative data structures: maps and keyword lists. Maps are the Elixir key-...

Bit fields tightly pack C and C++ structures to reduce size. This appears painless: specify the number of bits for members, and compiler does the work of co-mingling bits. The restriction is inability to take the address of a bit field member, since it is stored co-mingled. sizeof() is also disal...

A Singleton is designed to ensure a class only has one instance and provides a global point of access to it. If you only require one instance or a convenient global point of access, but not both, consider other options before turning to the singleton. Global variables can make it harder to reason...

Module Names In Elixir, module names such as IO or String are just atoms under the hood and are converted to the form :"Elixir.ModuleName" at compile time. iex(1)> is_atom(IO) true iex(2)> IO == :"Elixir.IO" true

In most cases, the spread operator *. is identical to calling .collect { it.________ }. def animals = ['cat', 'dog', 'fish'] assert animals*.length() == animals.collect { it.length() } But if the subject is null, they behave a differently: def animals = null assert animals*.length() == null...

In 1998, the there was a first publication of the standard making C++ an internally standardized language. From that time, C++ has evolved resulting in different dialects of C++. On this page, you can find an overview of all different standards and their changes compared to the previous version. The...
