Of course, in mathematical contexts, that can introduce confusion about whether you might mean subtraction, but it would be pretty silly to interpret a hyphenated number as a subtraction problem in the context of talking about Really Big Numbers, especially when there's a comma before the hyphen.
Hmmmm. In preview, my hyphenated number got split with WBR elements into segments too short for the hyphens ever to be used. I wonder if that will also happen in posting the comment.
There's always
