Description
Not sure if this is the right place to point this out, but:
I have been trying to manipulate the log output of the i.pca Grass7 function through QGIS, which outputs (I believe rounded) eigenvector values some of which can be -0.0000. This is a mistake as I believe there is no -0 and it does confuse other mathematical functions when using the output.

I'm not sure if this is a QGIS issue, or an GRASS issue. Can you show some screenshots demonstrating how the issue occurs?

It may be a GRASS issue indeed, if an issue in the first place. I have attached a screenshot of the log by QGIS
