Calculator widget on notification panel

FWIW, there does seem to be a problem with the Notification Calculator. In my case the calculator doesn't retain any calculation once Notifications is closed.

I use PCalc which includes a notification panel without a problem.

I have that same problem but different numbers.
After upgrade High Sierra my Calc widget default is 25,46 everytime.

After restart numbers are 25,46 and after press AC it goes 0.
So i can make calculations but if i switch other program and then go back to widget i see last numbers around of 0,1 second and it switch back to 25,46.

I have the exact same problem and it's frustrating. Thanks to mons.fractus I now get 0. But exactly like paulo555, "The only problem that remains is that the calculator does not retain the number of the last operation. After a few seconds the value returns to zero". Hopefully Apple is listening and working on this issue.

Hi

I have the same problem, but my "aficionado" number il 72.

I guess it simply keeps fixed the first result of a calculation made after the upgrade.

By the way... sometimes it's impossible to give keyboard focus to the calculator:

the only way is to close and open some times the side panel.

Bugs of the first release, I guess...

******EDIT: Right after posting this, the persistent number returned. Dang.

Rather than delete the file, open it and make a couple of minor edits.

In my case, the number 43.34.

The file contained one line of code with the persistent value.:

bplist00‘ WdisplayYregisterX\lastOperator\lastRegisterU43.34U43.34Q*Q2 #0=CIK M

I edited the line by replacing the stored value with an asterisk. See below.

bplist00‘ WdisplayYregisterX\lastOperator\lastRegisterU*U*Q*Q2 #0=CIK M

This allows for stored values to persist until cleared no matter how many times the notifications panel is opened and closed. But when cleared, the zero will persist. Calculations seemed to work OK, too.

If you backed up the file with a smiilar name, the bug will happen again. Once the change is confirmed, the bug file can be deleted.

Same here in different machines running High Sierra. Calculator is now impossible to use as values reset themselves if you click anywhere outside (e.g. looking for an entry value on the browser). Amazingly annoying.

Sorry, but this is not the solution. Deleting the file helps to erase the "random" number which is presented when opening the calulator-tab. But it only will be replaced by zero! In former OSX-versions you found the last result when opening the calculator but not in 10.13, this is the fault.

I couldn't find the link but one user said he talked to Apple and they purposely changed the Calculator to "zero out" instead of retaining the last value. I couldn't say.

Personally I use PCalc from the App Store.

Thanks - fixed the problem for me and the calculator works fine now. Didn't bother to back up the file as the only other files in the preferences directory were all marked 'security' so the calculator plist was the only notifications widget with a plist in this directory. This gave me confidence that deletion wouldn't have any lasting effect. Thanks again mons.fractus. Nice one.

Are you kidding me? How are we supposed to be able to retrieve numbers e.g. from multiple windows in an app, or even different parts of an email, to enter them into the calculator if it goes to 0 every time we change focus?

Are there any calculator apps that aren't 1) $10, and 2) full of scientific functions the average user doesn't need, that work with Notification Center? The app store is only showing about two dozen apps for Notification Center to begin with. It's maddening not to have an easily accessible calculator that works properly.

Just received a reply from the developer of the PEMDAS calculator widget. The newest version (3.1) "white calculator" requires you to restart the computer after installation to fix an issue with macOS causing the calculator to look distorted or missing graphical sections. After restarting my computer, v3.1 works perfect. If any of you who have posted your concerns/complaints with how after upgrading to High Sierra the calculator in Notifications resets to zero (which I previously stated in this discussion is how Apple developers programmed it to function now), or it repopulates with the total you had before upgrading, I encourage you to give this widget a try. Just follow my instructions above on how to set it up.

If what we want is having a visible calculator that retains the last total and even has the benefit to be moved around the screen as an overlay, then based on my experience, PEMDAS is the solution for me. I am not satisfied with the results deleting the .plist/.config file give since all it does it reset the total to zero the moment you go to another window, screen, open/close the Notification sidebar, etc.

Hi Shelia,

I installed the calculator from launchpad to my dock. Now the opening and closing of the notification window doesn't disturb me and calculator is all the time to be seen \o/ (once again Apple's engineers are...engineers)

I'm sorry, can I have more help. How do i find this location?

If i search 'this mac' for 'library' i only get one folder and that folder only contains a cache folder. If I search 'this mac' for a folder named 'containers' i get none.

Just chiming in to ask for an official fix. There is no way this behavior is "by design." I appreciate the PEMDAS alternative but I'm really looking for a calculator widget for the Today panel of the notification center. The official one used to work. It's crazy that it's been broken as long as it has. If there's a third-party widget that can be added to the notification center, I'll take that.
