It goes with KDE bug 412513
Captalizes the first letter for each number to be printed in text and for checks that have no fractional part prints No/100
Looks good to me. I have to admit that the whole logic seems very English centric and would not really apply well to a German or French translation from what I see. E.g. 92 in French translates to 80+12 and in German 92 translates to 2 and 90.
I just filed a wishlist (Bug 413713) to make the number to text conversion language specific. I also wonder if Bug 255492 (KMyMomney's currency system should be ported to use KDE currency support) might be relevant to this issue.
