View Options - Contour Criteria Legend - Digits for general format?

Hi,

 

 

I'm trying to figure out how Digits parameter in View Options works.

 

For exponent number format it works fine when I set 2 digits:

For general format, when I set 2 digits:

format_general.png

 

It has some influence but I don't get the logic. For 4 digits:

Can somebody explain the logic? Digits should not be used with general format, 0 must be set?
