These functions allow for arbitrary-length integers to be worked with using
|
|
the GNU <acronym>MP</acronym> library.

<para>
|
|
Most GMP functions accept GMP number arguments. These are shown in this
|
|
documentation as <classname>GMP</classname> objects. Most
|
|
of these functions will also accept numeric and string arguments, so long
|
|
as it is possible to convert the latter to a number. Also, if there is a
|
|
more performant function that can operate on the arguments (integers only),
|
|
then it will be used instead (this is done transparently). See also the
|
|
<function>gmp_init</function> function.

From PHP 5.6 onwards, the

<link linkend="language.operators.arithmetic">arithmetic</link>,
|
|
<link linkend="language.operators.bitwise">bitwise</link>, and
|
|
<link linkend="language.operators.comparison">comparison</link> operators
|
|
may be used with the <classname>GMP</classname> objects returned from
|
|
<function>gmp_init</function> and other GMP functions.

<simpara>
|
|
Large integers must be specified as strings - otherwise, PHP will coerce
|
|
them to floats, resulting in a loss of precision.
