This issue is similar to #885.
db.test.insert({data: 1605131049382900});
The value of data is displayed as 1.6051310493829e+15.0 in Tree mode, Table mode and text mode.
When you click on the value, and copy it (by pressing CTRL+C), it is copied in scientific notation as well.
The value is displayed correctly in Mongo CLI (i.e 1605131049382900).
I'm using Robomongo 0.9.0-RC9.
It works fine on Robomongo 0.8.5.
@alyyousuf7 thank you for reporting! I managed to replicate it. We will fix this issue in the future versions and get back to you with any news.

Any update?
Hi @alyyousuf7, currently we are busy developing some critical features like Replica Sets, Export/Import asap. Thanks for the reminder, we will consider to investigate this issue if we have the chance.
Additionally, I have done some testing, seems like using Robomongo insert/edit document dialogs to do the same operation works correctly. So as a workaround you can try:

So the problem seems to exist only when "db.test.insert({data: 1605131049382900})" is used on robomongo shell.
When the workaround Robomongo insert/edit document dialogs are used, the "Copy Value" is also working correctly. Of course, it is not very convenient to use insert/edit document dialogs all the time but until we have a chance to fix this issue, I hope this workaround will work and help you.
any update ?... ETA etc.. still happens in v1.1 and it's REALLY annoying to the point of making the client unusable.
Nothing yet? Still the same behavior in v1.2.1.
