After introduction of rounding off of discount there was a necessity for explanations.
Many users do not "love" a copeck in prices, and set round prices. But, using the systems of discounts, break usual prices and again get copecks. User facility of rounding off of sum of sale was therefore done at the use of discounts, but here an error stole up not notedly.
For an example: an user, not understanding, put rounding off to "5". That did turn out?
At a sale the sum of check made a 13 hrn., gave the discount of 5%, 13 - 5% = turned out rounded off a 12,35 hrn. and program to "5", in the total sold for a 15 hrn.!
Why? How did turn out so?
Here we understood here, that it is necessary to place points. The point is that values of rounding off are not coefficients or yet there what, namely by monetary items. In our case, rounding off was "5", id est rounding off of sum of purchase to the nearest five гривень(roubles), and the nearest five гривень were in a number 15!
First. We will paint values:
- 0,1= 10 cop. rounding off to the nearest 10 copecks
- 0,5= 50 cop. rounding off to the nearest 50 copecks
- a 1= 1 hrn.(rub) rounding off to the nearest a 1 hrn.(rub)
- 5= 5 hrn.(rub) rounding off to the nearest a 5 hrn.(rub)
- 10= 10 hrn.(rub) rounding off to the nearest a 10 hrn.(rub)
Second. And why to round off a to 10 hrn.? Values 5 and 10 entered for application in shops, that trade in a large domestic technique, expensive commodities, in general, where the sum of purchase is calculated by thousands and rounding off to five, and then we can ten hrn. take the liberty of.
What rounding off to put? you choose already coming from the prices, if for you inexpensive commodity, apply 0,1 and 0,5.
And example in conclusion, sum to payment: a 6,5 hrn. - 5 % = 6,175 hrn. Rounding off "0, 1" will give a 6,2 hrn., and rounding off "0, 5" will give a 6,5 hrn.
