If you think the American economy is bad, take heart that it's nowhere near the ultra-super-hyperinflation in Zimbabwe, once one of the richest countries in Africa. The country's central bank has recently issued a Z$100 billion note (yes, Z$100,000,000,000).
So, what would a Z$100 billion note buy you? About two loaves of bread (it won't even get you lunch - you'd need at least Z$250 billion for lunch).
So far this year, the country ravaged by hyperinflation has been forced to print 100-million, 250-million and 500-million notes in rapid succession. All of them are now almost worthless.
It has become common now for Zimbabweans to talk of their daily expenses in trillions (one trillion is 12 zeros).
When John Robertson pinned a chart to the wall of office naming numbers up to twice as long, he says he "raised a bit of a laugh" from his colleagues.
But for many officials and accountants, a quadrillion - a million billion - is the number of the day.
