Custom parameter rounding off metrics

Is there a custom parameter to round off the metics ?
It would be useful to round the metrics of interpolation so as to not end up with fractional numbers in the exported instances

If you have grid 1/1 and extremum points, then there shouldn’t be fractional metrics. Or how do you achieve them, and which exact metrics do you mean?

As I said in the other thread, those metrics are always rounded because they can only be stored in integers.

What problem do you have with those metrics?
