Hello,
I use exportDataCSV (D; fname; path) to write data to a file. It works from SM and Preview SMath Viewer. But when I create an exe file, the data is not saved. I discovered in the log file that an error is being generated.

A file of 2000 integers is recorded about 25 seconds. Is this normal?

Thanks in advance.

I think the problem is in the the Cephes Mathematical Library; if you create an executable without that library exportData.csv should work.

David, thanks for replay. I disabled the Cephes Mathematical Library. Now the file is not created in all cases.

Now the file is not created in all cases.

I've made a simple test file and it works.
WorksheetTest.sm (3.04 KiB) downloaded 837 time(s).

If you post a small example that doesn't works for you I might try to find the cause and fix the plugin.

David, I've posted almost full file. Another thing that seems strange to me is the very long (~ 2 min) saving to file time. Eksponentes_V5.sm (19.79 KiB) downloaded 814 time(s)..
The WorksheetTest works.

The problem has been solved. But its cause has not been eliminated. It was enough to change the Round (A) function to Round (A;0). There was no problem with the speed of writing, either.
