change column format view in View mode

How I can change column format view in View mode? For example, I have column (formula calculating) in view mode and it looks like 100324.1234124 and other fields like currency looks like 12000,00 I wondering why there different separator? comma and dot? And how I can change calculating field view format like 100324.1234124 => 100 324,12
