You cannot. See a C reference for details; in general, %g is required
to truncate trailing zeroes, and in %<m>.<n>g the <n> is the maximum
number of significant digits displayed (the total number both before
and after the decimal point).
If you need to preserve trailing zeroes, then you need to write code
to do that yourself, or use the %e format code (or maybe even %f).
For example,
>>> a = 1.234e-5
>>> print "%.6g" % a
1.234e-005
>>> print "%.60g" % a
1.234e-005
>>> print "%.6e" % a
1.234000e-005
>>> print "%.6f" % a
0.000012
