Yeah, the posted headline is just plain wrong. It was 1.4 billion Japanese Yen.

This is just getting confusing (and ridiculous), I dont' know if you're using long or short scale.

Currency conversion, plus bad editing/title, plus confusion around the short/long scale.

Sometimes, M = 1,000, and MM = 1,000,000

(edit: just came back realizing that this was a useless comment since they'd both be wrong here)

In this case it was apparently neither of those

Why the hell is M 1,000? Shouldn't you use k?

Mille is sometimes used (eg, CPM is Clicks Per Mille/Thousand)

Mille is latin for 1000 and therefore the roman numeral for 1000 is `M`.

It's pretty unlikely for anyone to use a mix of roman numerals and decimals to describe.. Anything.

It's used in accounting in certain companies. It probably depends on the company culture.

It's also sometimes used in the US for 1/1000 of a dollar for property taxes (mill levy).

Edited, thanks.

That's an order of magnitude better but to nitpick: the amount is closer to $13M ;)
