Hi,

While the output of (1) "seq -w -1e-2 9" prints the width as expected, the output of (2) "seq -w -1e-3 9" does not:
 (1) vs. (2)
-0.01 | -0.001
00.99 | 0.999
01.99 | 1.999
02.99 | 2.999
03.99 | 3.999
04.99 | 4.999
05.99 | 5.999
06.99 | 6.999
07.99 | 7.999
08.99 | 8.999

Similarly, see "seq -w -1e2 -98" vs. "seq -w -1e3 -998".

Can you kindly confirm that the bug was introduced 4 years ago in the following commit: http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=86e4b778b148bdd82395fdc312ce8d937f303e33

Best regards,
 Marcel
