<para>
Creates a GMP number from an integer or string. String
representation can be decimal or hexadecimal. In the latter case,
the string should start with <literal>0x</literal>.
Optional parameter <parameter>base</parameter> is available since
PHP 4.1.0.

<note>
<para>
It is not necessary to call this function if you want to use
integer or string in place of GMP number in GMP functions, like
<function>gmp_add</function>. Function arguments are
automatically converted to GMP numbers, if such conversion is
possible and needed, using the same rules as
<function>gmp_init</function>.
