The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

  {$N<+│->}
 
  Description
 
    Switches between two settings that control the kind of
    floating-point code generated by the compiler. The default
    is {$N-}.
 
    {$N+}  Generates 80x87 code for floating-point calculations. The
           resultant .EXE file will only run on an 80x87-equipped
           computer.
 
    {$N-}  Automatically detects the existence of an 80x87. If one is
           not present, software library calls perform floating-point
           calculations at run time.
