VARIANT_ROUND(3)							 1							  VARIANT_ROUND(3)

variant_round - Rounds a variant to the specified number of decimal places

SYNOPSIS

       mixed variant_round (mixed  $variant, int  $decimals)

DESCRIPTION

	Returns the value of $variant rounded to $decimals decimal places.

PARAMETERS

	      o $variant
		- The variant.

	      o $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(3) in PHP cor-
	      responds to VarAdd()  in the MSDN documentation.

RETURN VALUES

	Returns the rounded value.

variant_fix - Returns the integer portion of a variant

SYNOPSIS

       mixed variant_fix (mixed  $variant)

DESCRIPTION

	Gets the integer portion of a variant.

		- The variant.

RETURN VALUES

	If $variant is negative, then the first negative integer greater than or equal to the variant is returned, otherwise returns  the  integer
       portion of the value of $variant.

NOTES

       Warning

	       This  documentation is based on the MSDN documentation; it appears that this function is either the same as variant_int(3), or that
	      there is an error in the MSDN documentation.
