OS: WinXP, SuSE Linux
Submission from: (NULL) (137.208.41.195)
The seq-command produces unnescessary inaccurate results, which can be extremely
annoying. I absolutely do not see the nescessity of numerical garbage to appear
in the following simple case. E.g. try this:

digits=2 )
Output looks like:
[1] 0.000000e+00 -7.105427e-15 0.000000e+00 0.000000e+00 -7.105427e-15
-7.105427e-15 0.000000e+00 0.00...

An even simpler case may help explain why this is not *unnecessary*
inaccuracy.
