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
<TT
CLASS="constant"
><B
>NULL</B
></TT
>), 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"
>VARIANT</A
> class. COM and DOTNET objects
will have the value of their default property taken and used as the variant value.
</P
><P
> 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.
