Hi Tom, Andrew,
Could you let me know whether this issue will be addressed by a bug fix, and if so which version(s) would be targeted and about how long it will take?
We need this information for our own planning purposes.
Thanks
Mike

Returning a truncated integer result seems preferrable to reporting an error to me.
Do you think this issue will be addressed with a fix? If so, what version would it be made in, and roughly how long would a fix take?
Thanks
Mike

Oh, thanks ... I was wondering what locale it had chosen, but did not know how to find out.

Hmm. That doesn't seem too helpful. Between throwing an error and returning "123", seems like the latter would be better.
Do we want to be bug-compatible here?
