I am trying to create a program where you enter an how much you owe and how much you pay and then the code returns a JOptionPane message telling you how much of each bill/coin to give.
Example: I owe 14.47 and I pay 20, the return statement will be "five: 1, one: 0, quarter: 2, etc."
I pretty much have the code done however, for some reason the program will give one less penny than is needed. I've determined that it is a round off error, but I have no idea how to solve it or do it any other way.
private double owed;
private double paid;
private ArrayList<Currency> currency;
private double due = paid - owed;
public CashRegister(double owed, double paid, ArrayList<Currency> currency)
{
this.owed = owed;
this.paid = paid;
this.currency = currency;
due = paid - owed;
}
public String changeDue()
{
String output = "";
for(int x = currency.size() - 1; x >= 0; x--)
{
double value = currency.get(x).getValue();
int holder = (int)(due/value);
if (holder >= 1)
{
due = due - (holder*value);
output = output + currency.get(x).getName() + ": " + holder + "\n";
}
else
output = output + currency.get(x).getName() + ": " + holder + "\n";
}
return output;
}
Essentially, the holder contains the amount of the bill/coin needed. It needs to be a whole number. I'm pretty sure that's where the error is, however it could also be the "due = due - (holder*value)." Please help as I am completely lost. If you know another way to truncate decimals or something lmk if you think that would solve the issue.
Hi,
I’m converting a symbolic expression into a function using matlabFunction in order to evaluate it in an optimization routine. However, I noticed that if I use subs with a value I get a result which exactly matches my expected results for the function. If I evaluate the result using the same value but in the matlabFunction generated function, the result has errors in the 5th or 6th decimal place which is fairly significant. Is there a way to fix this? I tried turning off the optimize option for matlabFunction but the errors still persist.
So I have some spatial R-T-Z (radius/angle/elevation) data that unfortunately has a lot of round-off on the Radius dimension.
I need to calculate the 2nd derivative off this data and thus it needs to be smoothed/filtered somehow. I currently use a typical gaussian/uniform blur but I was just wondering,
are there other kinds of techniques out there that can take care of error due to discrete binning or data roundoff?
EDIT: For reference for future searchers, I found that the Savitzky-Golay filter seems to produce great results.

Hello, I write this post today, as I find myself in a bit of a conundrum.
While calculating the fuel and range for a flight plan (theoretical, not flying yet), I found that after rounding flight time and range, my Take Off Fuel goes from 9337,48KG to 9413,24KG.
Does anyone know what is (if there is one) the margin of error when calculating weights, fuel, and etc?
Thanks!
EDIT: Thank you all for your input!
I have a question about round off error and sig figs in Lab Reports. When filling in data tables that require calculations do you leave your unrounded values in the tables for further calculations or would you round those values to the appropriate number of sig figs that match your most precise measuring device? While I understand that rounding off these values too soon will result in round off error for further calculations, it seems inappropriate to leave the unrounded values of something to 8-10 sig figs even if they aren't part of the final calculation and only values shown in your data table.
cheers
2018 Accord Touring 2.0T. Been having the well documented problem of ACC randomly turning off due to CMBS error.
I took it to dealership and told them about the TSB that is supposed to fix the issue. They said it was already installed. Test drove the vehicle and they were able to duplicate the error. They said it could be due to 2 foot driving (don’t do that), resting foot on brake (don’t do that), or due to aftermarket windshield (I don’t believe this because it works fine most of the time). Has anyone else continued to have this issue after the TSB patch was allegedly applied? I’m tempted to order Ktuner and flash the software myself, as it looks like they have integrated the patch into their tune now.
Any thoughts or recommendations? I love the vehicle but this is a big feature to have that doesn’t work half the time.
Thanks!
Been happening a LOT today, I watch a whole video and it either says playback error at the very end, or finishes normally, but I don't get the ad reward / upgrade reduction.
Anyone else experiencing this lately? Is there a way around it? I hate watching the whole ad and getting nothing for it.

Then he tells you that he even took off 1 point for people who had 0.22% error (yes, 0.22%)
