Please add VT_NULL argument handling and tests. This function is 
returning error on Sgn(Null) call.

[PATCH 3/4] vbscript: Implemented Sgn(try 4)

[Shuai Meng]

Thank you Piotr.
Yes, Sgn(Null) will return error, so do conversion functions. I wonder
whether should I send some patches to fix the conversion functions.
As for Sgn(Null), I don't know how describe this error, I mean, I can't
match the error_const_value between wine and windows document. For example,
when Err.number = 458, it is described as DISP_E_BADVERTYPE in wine while
in windows document it is Variable uses an Automation type not supported in
VBScript <http://msdn.microsoft.com/en-us/library/93dk459a(v=vs.84).aspx>  (
http://msdn.microsoft.com/en-us/library/xe43cc8d(v=vs.84).aspx)

I have found that when Sgn(Null) is called, Err.number = 94, this error is
described as Invalid use of Null
<http://msdn.microsoft.com/en-us/library/c6ct86c6(v=vs.84).aspx>, but I
can't find the correspond description in wine/include/winerror.h.

So I shall be very grateful if you can offer some hints.
