I use the Calculated Number Field (which works very well) but when I try to do Excel export, I see a locale issue.
The default language of our JIRA is French, my profile setting is English(UK). With these settings, a decimal number from a normal number field has the following format: 68.71
From the calculated number field, I have the following format: 68,71
If I change my profile to French, then both have the format 68,71
I think it would be good if you could follow the locale also for calculated field (otherwise an Excel export sees the number as a text, and not a number)
