<!-- $Revision: 1.2 $ -->
<note>
<para>
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
variant_add() in PHP corresponds to VarAdd() in the MSDN documentation.
