I remember this showing up years ago in an online java mortgage calculator
giving embarrasingly far-out results.
Only there the bug was the "other way round".
In this case my opinion is that it is behaving as expected and no error.
If the programmer writes 070 he probably means octal, but that doesn't mean
every user and zero-padded string means octal.
I hope the behaviour is not changed; or we may get bad mortage calculators
again.
