I recently received this email from a student:

She [a relative living in Zimbabwe] wanted to know the name of this figure: 10,000,000,000,000,000,000,000,000 (1 with 25 zeroes) ? This figure is the equivalent of what 1 trillion dollars is today, however in the old currency (before they knocked 13 zeros off). The banks actually took off another 6 zeros last week as their systems couldn’t handle the numbers anymore.

I don't know the name of that number--anyone? Bueller?

BTW, Cato has a nifty page on Zimbabwe's hyperinflation.

UPDATE: A kind reader informs me the number is 10 septillion.
