<blockquote class="note"><p><strong class="note">Note</strong>:
<p class="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
<strong><code>NULL</code></strong>), 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 <a href="class.variant.html" class="xref">VARIANT</a> class. COM and DOTNET objects
will have the value of their default property taken and used as the variant value.
</p>
<p class="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
<span class="function"><a href="function.variant-add.html" class="function">variant_add()</a></span> in PHP corresponds to <em>VarAdd()
</em> in the MSDN documentation.
