When exporting transactions to CSV (in this case from a Mutual fund account), the values in the Rate/Price column are displayed as fractions (e.g. 88 + 54/113). Although numerically correct, if we consider the export functionally aimed towards the integration of data in other software, assuming that other software will understand the fractional representation is probably a little bit optimistic (and generally wrong) In order to maintain compatibility/functionality, a possible solution would be to add a new checkbox ("Export Rate/Price as decimal"?) to the 1st screen of the wizard ("Choose Export Settings").
Or make the exporter use the force prices to decimal preference (GNC_PREF_PRICES_FORCE_DECIMAL "force-price-decimal").
I have changed the CSV transaction exporter to follow the Preference setting... 'General->Force Prices to display as decimals' for the Price/Rate output. This will be in version 4.0
