Yes, I think you're right. The dot is in the middle; I wasn't aware that meant multiply. I asked this on behalf of an American friend (I'm from the UK). I noticed the decimal point was oddly placed, but I thought Americans displayed differently or something... Kind of stupid now that I think about it.

Well I guess that's settled then. Thanks a lot!

 May 11th, 2017, 01:20 AM #7 Global Moderator   Joined: Dec 2006 Posts: 20,931 Thanks: 2207 The raised dot used to be the conventional decimal separator in the UK, with an unraised dot being used at the end of a sentence and for multiplication. The standard was changed quite some time ago (possibly in the 1980s), probably due to pressure from mainland Europe, and because the raised dot wasn't available on most computer keyboards. Similar pressure to replace the "," in, say, "1,000" with a space ("1 000") was less successful.
