Stefan:

    ... and in my language (xHarbour -- eXtended Harbour: a language that is 
compiled into C functions using the old Borland BCC 5.5.1 verion in this 
instance), the statement and results are:

   nTest := -5.5 % 3
   ? ntest            // result -2.5
   ? str(nTest)    // result -2.5  -- same
