try the g and G specifiers like:

>>> "%g" % 1.5000
1.5
>>> "%g" % 1.50002
1.50002
>>> "%1.3g" % 1.50002
1.5

the default precision for g is, I think, .8. But it doesn't quit work like
advertised (on my system at least), somehow it influences the field width
as wel:( So you get 8 chars atmost, including the point and the numbers
before the point. So be carefull to avoid the following:

>>> "%1.3g" % 111.50002
112
