[Python-Dev] Float formatting and #

Is there a reason why the "alternate format" isn't documented for float
conversions in http://docs.python.org/lib/typesseq-strings.html ?

'%#8.f' % 1.0 keeps the decimal point while '%8.f' % 1.0 drops it.

Also, for %g the alternate form keeps trailing zeroes.

While at it, I noticed a difference between %f and %g:

'%.3f' % 1.123 is "1.123" while
'%.3g' % 1.123 is "1.12".

Is that intentional?

Georg
