Parameters				  				   								    								     variant												     								      				       The variant.				      				     								    								    								     decimals												     								      				       Number of decimal places.				      				     								    								   								  				  Note: 								 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 VARIANT class.  COM and DOTNET objects				 will have the value of their default property taken 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.																 								 				  Return Values				  				   Returns the rounded value.
