On 2 February 2009, a third redenomination took place, in which the RBZ removed 12 zeros from the currency, with 1,000,000,000,000 (third, ZWR) Zimbabwe dollars being exchanged for 1 new (fourth, ZWL) dollar.[1] Therefore, the fourth dollar (ZWL) is equivalent to 10,000,000,000,000,000,000,000,000, or 1×1025 or 10 septillion first dollars (ZWD) (or 1 trillion third dollars). Although the dollar was abandoned on 12 April 2009, exchange rates were maintained at intervals for some months.
