This test of floating-point arithmetic is likely to show
differences from platform to platform because of differences
in floating-point precision and details of the routines that
convert floating-point numbers to strings.  If the values
produced in local tests are approximately the same in magnitude
as shown in the standard results, there's nothing to worry about.
In addition, some platforms may show 0.0 as "-0.0".  You can
ignore this if you wish.
