The PayPal error 589023 in particular has this meaning:

If a fractional amount is rounded due to currency conversion, funds could be lost

This means that you are providing a payment value that needs to be rounded up or down to the nearest cent/penny/[smallest unit of currency] before being submitted to PayPal (as described here).
