<para>
Divides <parameter>a</parameter> by <parameter>b</parameter> and
returns the integer result. The result rounding is defined by the
<parameter>round</parameter>, which can have the following
values:
<itemizedlist>
<listitem>
<simpara>
<parameter>GMP_ROUND_ZERO</parameter>: The result is truncated
towards 0.
</simpara>
