Good point. I can't edit the main post anymore, so it might cause some confusion still.
To make it clear, the purpose was to express 24 million dollars
My bad...sorry about that, I did mis-read the post. I've seen period use, but normal operations in $US transactions is not a period, but commas. $24,000,000. I originally mis-read it and thought $24,000.000 so I was thinking twenty-four thousand.
