Round float values in "terms" panels (terms_stats / mean)

[andrebalg]

I have a request similar to #697 , but for the "terms / terms_stats" panels instead of the "histogram" panels. The float values show at least 15 digits in the legend, whereas it would be preferable to display, say, 4 or 5 digits.

I have a similar situation - my doubles when using terms/term_stats "total" are very lengthy from a precision display standpoint (i.e. below). Would love a way to round them to, say 2 places after the decimal.

Is the commit merged to master?

This is something that field formatters will allow you to take control of. Please follow #1543 for updates.
