[Kmymoney-devel] [Android Port] Help with computing the account balance

[Eric Bonney]

Thanks Allan,

I can easily just leave it at say -123.32/100 and it will work too but was
hoping to work more like KMM and I can't figure out how you jumped from the
12352/100 to 6266/50 then down to 3133/25.

Did you just get the GCD and then divide by that?
