The code is taken from:
PHP Code:

see listing 15.1 and 15.2. Most of the code is exactly the same as the one I posted with the exception of the main function. According to the book -and I debugged it in order to verify it- this behavior is due to the constructor from String.

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. SEE ALSO
