€{{chiven.K0}} is deposited on {{chiven.d1.strftime('%d.%m.%Y')}}
and withdrawn {{chiven.d2.strftime('%d.%m.%Y')}} with amounted interests.
The bank calculates full calendar years (1.1. - 30.12, 12x30M, 360T)
with compound interest and not full years linearly (combined or practical interests).
The annual interest rate is {{chiven.i}}%.
Calculate the capital at the time of withdrawal.
%chq(0)

are fractions) (theoretical interest), what would the difference of this
capital from the previously calculated one?
