Wrong numeric value displayed in Grid but correct in Text output

Description

When I select a column of data type REAL (float4) in Postgres, I get to see a value in the Grid output that is not the correct value from the database. It appears as if the value has been rounded and several fractions have been added:

When checking the Text output, the value is displayed correctly:

Interestingly, the same value is present in the Grid when I double-click into the value:

PostgreSQL returns a result set with a single column whose type has no bounds on its precision. When DBeaver displays its value, it checks its precision and formats it accordingly by exposing all these weird digits thanks to the rounding errors.

It looks like the editor, when opened, receives another value that wasn’t formatted. Perhaps we need to look into that.

Given that the right value is there when you double-click on it, I think it’s more like DBeaver works… 😃 I appreciate that it takes the value and converts it into a float for display, but the correct value is there in the grid. I just can’t see why you would run through the conversion at that stage but then again, I don’t know what the option is really good for, to begin with. Anyway, thanks again!
