Problem with significant figures

[emanuele_cardinali]

Hello everyone,
I did a simple fit on a histogram.
I would like to know how to check the significant figures (for the errors) that appear on the table at the top right.

I would like to know how to check the significant figures

These figues are the fit parameters (the result of the fit).
What do you mean by “check” ?
