"Six months ago Zimbabweans were told that they would be able to exchange bank account balances of up to 175 quadrillion Zimbabwe dollars for just 5 U.S. dollars – a heartbreaking sum, given that it was many people's life savings."
that's just embarrassing. for your currency units to get up to 175 quadrillion (i don't even know how many zeros that is) means you've faced extended periods of hyperinflation. it's like when you have an Excel error in your balance sheet model and your cash balances increases exponentially. except this is IRL for zimbabwe.
