    As often mentioned here, "style" is a set of guidelines issued by somebody and whether you follow it, depends upon (choose one) your inclination, whether somebody is paying you to follow it or whether it's imposed by somebody upon whom you depend for academic approval.

    Having said all of that, I'll point out that U.S. newspaper style would be "... an estimated $5 billion."
