QGIS2+: values shown in scientific notation

Description

Right now, values like "4176000000" are displayed as "4.176e+06" (the scientific notation). Seems like printf '%g' is used?

The problem appears anywhere, values are shown:
  • attribute tables
  • tooltips
  • legend
  • etc

And it's around for a pretty long time: #15880

After a lively discussion on the QGIS-mailing list, the following options might be useful:
  • never show values in scientific notations
  • mixup like now
  • always show scientific notations

A simple workaround might be casting the full float/double values to string for displaying them.

Giovanni, this report is more global and proposed some solutions to the issue.
If there's a report to close, should it not be #15880 instead?

Sorry, still doesn't seem to be fixed: I'm on 6ddd9ab0c7 (from 2018-03-30, which is newer than 054470f0 from 2018-03-28) and "attribute table" and "identify tool" still show scientific notation.

#12 Updated by Andreas Wicht about 2 years ago

I currently have the issue that QGIS 2.18.18 displays an ID as 1385998 (Identify Tool) whereas QGIS 3.0.1 shows that features' ID as 1.386e+06 which is even worse...

any news on the current state of development?

#13 Updated by Tobias Wendorff about 2 years ago

On some places it has been fixed, on many it hasn't. See attachment.

I'm on QGIS3, GIT build af8d9eb1a6
