Have I Finally Become Dense? (Rounding Issue)
I've been at PHP for more years than I care to say... And now I think I've become dense or maybe I should quit my job and become a sanitation driver. :-)
Client has a total * tax rate = something like .6201... Their POS system (not PHP) rounds .6201 up to .63 - which makes zero sense to me...
How in the world would I force my round function to insist that 0 in the thousands place is high enough to round up to 3. This defies mathematics and I'm stumped.
You say this is a PoS (I'm assuming you mean Point of Sale and not Piece of S**t).
A previous job of mine was a manager at a new start-up resturant. I worked closely with the PoS guys, so if something went wrong I could fix it on the spot.
Through this, I became very familiar with PoS's.
If there is any thousandth's decimal, most, if not all, PoS's will always round up - why? Money. Those fractions of a penny add up after a full day of sales. So if it didn't round up, the business could potential take a big hit, think 200 orders a day, each with .004 cents cut from that is .80 cents. .80 cents a day is $292 dollars a year - and that's thinking very conservatively.
For example, have you ever seen Office Space? It is the same principal.
Now as for your question, I'm not completely sure what you are asking...
You would add 0.005 before rounding. .6201+.005 = .6351, which rounds up to .63
always round up!
