need fix to currencies conversion from IQD to USD#926

I want my customer to see item price in IQD but the online payment going to be in USD, so my problem is with the exchange rate of the USD, it is look like it is 10 times bigger from what it should be for example if i sell one item for 300 IQD and I perches it with USD I’m going to be changed 2.29 USD but it should be 0.229 it means 10 times bigger from what it’s should be . maybe there’s problem with the zeros in IQD currency
