In German, this is called "Periode". So you're right, indeed, it's
a Denglish term.

The proper name for the overline seems to be "vinculum":
Unfortunately, its usage is not limited to recurring decimals and I'm
also not sure whether this term is really commonly used. To me, it
sounds rather technical.

In my opinion, it would be better to give the argument a better
name, as well. For instance, "reccuring" would be an obvious option - or
even "vinculum", but see above...
