I have the same problem with Cross-currency payments. I have found that Xero only allows 6 significant figures (or 5 decimal places) which isn't enough as it constantly throws up US$.01 or US$.02 rounding's or FX differences, which would be alleviated by using 6 decimal places or 7 significant figures. As a long term user of multicurrency systems, I would highly recommend the Xero increase the fx rates allowed to 6 decimal places or 7 significant figures to improve the fx conversions on Cross-currency transactions and eliminate fx differences.
