Note :
As with all the variant arithmetic functions, the parameters for this function can be either a PHP native type (integuer, string, floating point, boolean or
null), or an instance of a COM, VARIANT or DOTNET class. PHP native types will be converted to varians using the same rules as found in the constructor for the variant class. COM and DOTNET objects will have the value of their default property taquen and used as the variant value.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.
