<!-- Cautions -->
<!ENTITY caution.cryptographically-insecure '<caution xmlns="http://docbook.org/ns/docbook">
 <para>
  This function does not generate cryptographically secure values, and <emphasis>must not</emphasis>
  be used for cryptographic purposes, or purposes that require returned values to be unguessable.
 </para>
 <para>
  If cryptographically secure randomness is required, the <classname>Random\Randomizer</classname> may be
  used with the <classname>Random\Engine\Secure</classname> engine. For simple use cases, the <function>random_int</function>
  and <function>random_bytes</function> functions provide a convenient and secure <acronym>API</acronym> that is backed by
  the operating system’s <acronym>CSPRNG</acronym>.
 </para>
</caution>'>

<!ENTITY caution.mt19937-tiny-seed '<caution xmlns="http://docbook.org/ns/docbook">
 <para>
  Because the Mt19937 (“Mersenne Twister”) engine accepts only a single 32 bit integer as the
  seed, the number of possible random sequences is limited to just 2<superscript>32</superscript>
  (i.e. 4,294,967,296), despite Mt19937’s huge period of 2<superscript>19937</superscript>-1.
 </para>
 <para>
  When relying on either implicit or explicit random seeding, duplications will appear
  much earlier. Duplicated seeds are expected with 50&#37; probability after less than
  80,000 randomly generated seeds according to the birthday problem. A 10&#37; probability
  of a duplicated seed happens after randomly generating roughly 30,000 seeds.
 </para>
 <para>
  This makes Mt19937 unsuitable for applications where duplicated sequences must not happen with
  more than a negligible probability. If reproducible seeding is required, both the
  <classname>Random\Engine\Xoshiro256StarStar</classname> and <classname>Random\Engine\PcgOneseq128XslRr64</classname>
  engines support much larger seeds that are unlikely to collide randomly. If reproducibility
  is not required, the <classname>Random\Engine\Secure</classname> engine provides cryptographically
  secure randomness.

 As with all the variant arithmetic functions, the parameters for this function
 can be either a PHP native type (integer, string, floating point, boolean or
 &null;), or an instance of a COM, VARIANT or DOTNET class.  PHP native types
 will be converted to variants using the same rules as found in the constructor
 for the <xref linkend="class.variant"/> class.  COM and DOTNET objects
 will have the value of their default property taken and used as the variant value.
</para>
<para>
 The variant arithmetic functions are wrappers around the similarly named
 functions in the COM library; for more information on these functions, consult
 the MSDN library.  The PHP functions are named slightly differently; for example
 <function>variant_add</function> in PHP corresponds to <literal>VarAdd()
 </literal> in the MSDN documentation.
