XLL's excel's dll's

I would like to see and example of an xll written in turbo pascal or
delphi.  I have the excel developers kit, and can write dll's in c and
pascal.  

But there was a fairly criptic one line comment about passing of
floating point variables with Borland C, and a work around due to
borlands use of the other stack.

Is this the same for delphi?

And any examples appreciated.  Also examples of calls to the excel
api.
