+ Abstract Datatype for the Annotations of the Erlang Compiler
+ </modulesummary>
+
+ <description>
+ <p>This module implements an abstract type that is used by the
+ Erlang Compiler and its helper modules for holding data such as
+ column, line number, and text. The data type is a collection of
+ <marker id="annotations"><em>annotations</em></marker> as
+ described in the following.</p>
+ <p>The Erlang Token Scanner returns tokens with a subset of
+ the following annotations, depending on the options:</p>
+ <taglist>
+ <tag><c>column</c></tag>
+ <item><p>The column where the token begins.</p></item>
+ <tag><c>location</c></tag>
+ <item><p>The line and column where the token begins, or
+ just the line if the column unknown.</p>
+ </item>
+ <tag><c>text</c></tag>
+ <item><p>The token's text.</p></item>
+ </taglist>
+ <p>From the above the following annotation is derived:</p>
+ <taglist>
+ <tag><c>line</c></tag>
+ <item><p>The line where the token begins.</p></item>
+ </taglist>
+ <p>Furthermore, the following annotations are supported by
+ this module, and used by various modules:</p>
+ <taglist>
+ <tag><c>file</c></tag>
+ <item><p>A filename.</p></item>
+ <tag><c>generated</c></tag>
+ <item><p>A Boolean indicating if the abstract code is
+ compiler generated. The Erlang Compiler does not emit warnings
+ for such code.</p>
+ </item>
+ <tag><c>record</c></tag>
+ <item><p>A Boolean indicating if the origin of the abstract
+ code is a record. Used by Dialyzer to assign types to tuple
+ elements.</p>
+ </item>
+ </taglist>
+ <p>The functions
+ <seealso marker="erl_scan#column/1">column()</seealso>,
+ <seealso marker="erl_scan#end_location/1">end_location()</seealso>,
+ <seealso marker="erl_scan#line/1">line()</seealso>,
+ <seealso marker="erl_scan#location/1">location()</seealso>, and
+ <seealso marker="erl_scan#text/1">text()</seealso>
+ in the <c>erl_scan</c> module can be used for inspecting
+ annotations in tokens.</p>
+ <p>The functions
+ <seealso marker="erl_parse#map_anno/2">map_anno()</seealso>,
+ <seealso marker="erl_parse#fold_anno/3">fold_anno()</seealso>,
+ <seealso marker="erl_parse#mapfold_anno/3">mapfold_anno()</seealso>,

+ anno_from_term()</seealso>, and
+ <seealso marker="erl_parse#anno_to_term/1">
+ anno_to_term()</seealso> in the <c>erl_parse</c> module can be
+ used for manipulating annotations in abstract code.

+ <modulesummary>Pseudo random number generation</modulesummary>
+ <description>
+ <p>Random number generator.</p>
+
+ <p>The module contains several different algorithms and can be
+ extended with more in the future. The current uniform
+ distribution algorithms uses the
+ <url href="http://xorshift.di.unimi.it">
+ scrambled Xorshift algorithms by Sebastiano Vigna</url> and the
+ normal distribution algorithm uses the
+ <url href="http://www.jstatsoft.org/v05/i08">
+ Ziggurat Method by Marsaglia and Tsang</url>.
+ </p>
+
+ <p>The implemented algorithms are:</p>
+ <taglist>
+ <tag><c>exsplus</c></tag> <item>Xorshift116+, 58 bits precision and period of 2^116-1.</item>
+ <tag><c>exs64</c></tag> <item>Xorshift64*, 64 bits precision and a period of 2^64-1.</item>
+ <tag><c>exs1024</c></tag> <item>Xorshift1024*, 64 bits precision and a period of 2^1024-1.</item>
+ </taglist>
+
+ <p>The current default algorithm is <c>exsplus</c>. The default
+ may change in future. If a specific algorithm is required make
+ sure to always use <seealso marker="#seed-1">seed/1</seealso>
+ to initialize the state.
+ </p>
+
+ <p>Every time a random number is requested, a state is used to
+ calculate it and a new state produced. The state can either be
+ implicit or it can be an explicit argument and return value.
+ </p>
+
+ <p>The functions with implicit state use the process dictionary
+ variable <c>rand_seed</c> to remember the current state.</p>
+
+ <p>If a process calls <seealso marker="#uniform-0">uniform/0</seealso> or
+ <seealso marker="#uniform-1">uniform/1</seealso> without
+ setting a seed first, <seealso marker="#seed-1">seed/1</seealso>
+ is called automatically with the default algorithm and creates a
+ non-constant seed.</p>
+
+ <p>The functions with explicit state never use the process
+ dictionary.</p>
+
+ <p>Examples:</p>
+ <pre>
+ %% Simple usage. Creates and seeds the default algorithm
+ %% with a non-constant seed if not already done.
+ R0 = rand:uniform(),
+ R1 = rand:uniform(),
+
+ %% Use a given algorithm.
+ _ = rand:seed(exs1024),
+ R2 = rand:uniform(),
+
+ %% Use a given algorithm with a constant seed.
+ _ = rand:seed(exs1024, {123, 123534, 345345}),
+ R3 = rand:uniform(),
+
+ %% Use the functional api with non-constant seed.
+ S0 = rand:seed_s(exsplus),
+ {R4, S1} = rand:uniform_s(S0),
+
+ %% Create a standard normal deviate.
+ {SND0, S2} = rand:normal_s(S1),
+ </pre>
+
+ <note><p>This random number generator is not cryptographically
+ strong. If a strong cryptographic random number generator is
+ needed, use one of functions in the
+ <seealso marker="crypto:crypto">crypto</seealso>
+ module, for example <c>crypto:rand_bytes/1</c>.</p></note>
