It's probably not, unless you've calculated that it is? It's not at all common any more, led by financial interoperability I think.

(Unfortunately in my opinion: it seems more logical than the American/standard billion. We go up to nine until we run out of units and start on tens, until we run out at nine tens and nine and start on hundreds, until we run out at nine hundreds and nine tens and nine and start on thousands, until we run out at nine hundred and nine tens and nine thousand and nine hundreds and nine tens and nine and start on millions. Why then only go to nine hundred and nine tens and nine million (...)? It breaks the pattern of using all the expressable numbers until you run out and have to start a new word.)
