I couldn't find other issues where #1 and #2 are addressed. This
is from py3k:


#1:

>>> format(float('nan'), '+08.4')
'+0000nan'
[70141 refs]
>>> format(Decimal('nan'), '+08.4')
'    +NaN'


#2:>>> format(float(123), "00")
'123.0'
[70141 refs]
>>> format(Decimal(123), "00")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    raise ValueError("Invalid format specifier: " + format_spec)
