Par prakticnih pitanja vezana uz izvjestaje

"Covjek hoce za neki proizvod imati maloprodajnu cijenu 100,00 kn. Ja
unosim cijenu veleprodajnu koja je unesena u decimalnom formatu (koriste se
2 decimale). To je 100/1,22=81,97 kn. Dakle, covjek ocekuje da kada u
stavku na racunu doda 6 komada te robe total bude 600 kn sto naravno nije.
Kako se prakticno rjesava ovaj problem?"

Apple List: 64 bit - double variables

If you are dealing with monetary values, you almost certainly should not be
using base-2 arithmetic. See http://www2.hursley.ibm.com/decimal/ and
http://www2.hursley.ibm.com/decimal/decifaq1.html for more information.

..., you can use a library such as decNumber: http://www.alphaworks.ibm.com/tech/decNumber

Fractured YEARFRAC and Discounted DISC

"Why should day counting be complicated? Just count how many days
between the two dates and you are done, right? Indeed, everywhere but
in finance it is simple.

Some of the complications are for historical reasons, to try to make hand
calculations easier in the pre-computer era. Also, these conventions made
the calendar more regular, so financial instruments were less distorted by
calendar irregularities like leap years or variable length months. If you
assume a year is exactly 360 days in 12 months with 30 days each, then
some things in life are simpler."
