Not officially, so far as I know, but if you're willing to risk using a
private implementation detail that is subject to change:
>>> decimal.Decimal('000123.45000')._int
'12345000'
However, sometimes you may need to inspect the exponent as well:
>>> zero = decimal.Decimal('0.00000000')
>>> zero._int
'0'
>>> zero._exp
-8
