 _fpreset()              Reinitialize Floating-Point Math Package

 #include   <float.h>

 void       _fpreset(void);

    _fpreset() resets the floating-point math package.  This is
    particularly valuable if a program using the 8087/80287 coprocessor
    runs under versions 1.x of MS-DOS, because a child process loaded and
    executed by system(), exec...(), or spawn...() might change the
    floating-point state of the calling process.

    A program that uses the 8087/80287 numeric coprocessor should avoid
    calling exec...(), spawn...(), or system() during evaluation of a
    floating-point expression and should call  _fpreset() after any of
    these calls if it is possible that the child process used the numeric
    coprocessor to perform a floating-point operation.

       Returns:     Nothing
