-     <function>number_format</function> returns a formatted version of
-     <parameter>number</parameter>.  This function accepts either one,
-     two or four parameters (not three):
-    </para>
-    <para>If only one parameter is given,
-     <parameter>number</parameter> will be formatted without decimals,
-     but with a comma (",") between every group of thousands.
-    </para>
-    <para>
-     If two parameters are given, <parameter>number</parameter> will
-     be formatted with <parameter>decimals</parameter> decimals with a
-     dot (".") in front, and a comma (",") between every group of
-     thousands.
-    </para>
-    <para>
-     If all four parameters are given, <parameter>number</parameter>
-     will be formatted with <parameter>decimals</parameter> decimals,
-     <parameter>dec_point</parameter> instead of a dot (".") before
-     the decimals and <parameter>thousands_sep</parameter> instead of
-     a comma (",") between every group of thousands.
-    </para>
-    <note>
-     <para>
-      Only the first character of <parameter>thousands_sep</parameter>
-      is used.  For example, if you use <literal>foo</literal> as
-      <parameter>thousands_sep</parameter> on the number
-      <literal>1000</literal>, <function>number_format</function> will
-      return <literal>1f000</literal>.

-      For instance, French notation usually use two decimals,
-      comma (',') as decimal separator, and space (' ') as
-      thousand separator. This is achieved with this line :
