I wouldn't. The documentation is fairly clear that the '%g' specifier is
what gets used by default. If you want something else, you need to
specify the format via the -f option; for example:

$ seq  -f %.2f 0.00 0.01 0.90| grep "\.[0-9]0$"
0.00
0.10
0.20
0.30
0.40
0.50
0.60
0.70
0.80
0.90

In any case, I think John's advice is wisest: don't use floating point
math for iteration. These are exactly the sorts of troubles you get when
doing so.
