Always
ShortVal = (SHORT)(ShortVal + DoubleVal)
or in C++ - Style
ShortVal = static_cast<SHORT>(ShortVal + DoubleVal)
should compile without problems.
***But*** using floating point arithmetic within kernel mode isn't trivial
and should be avoided. There are several discussions in news goups and - as
far as I can remember - even in this mailing list regarding this subject.
The /Wx (Treat all warnings as errors) compiler option can not be overridden
if once added to compiler command line. You could tinker with some build
utility macros like MSC_WARNING_LEVEL to work around your problem but these
are IMHO bad practices.
