John,

I don't know exactly what you think is not clear in my question and how examples can help to clarify.

In text what I use the comma is the decimal separator.
The dot is a thousand separator.
submatch() doesn't recognize the thousand separator and doesn't recognize the comma as decimal separator.
submatch() handles different regional settings as the one in my country.
Is there a way to let submatch() my regional settings?
If not .. do I have to convert all xx,xx numbers to xx.xx numbers (substitute dot for comma) and all x.xxx.xxx numbers to xxxxxxx numbers (removing the thousand separator)?

p.e.
see these examples:
please put these values in a new buffer:
1.000.000 25,20 10.15 200

These are the the different examples:

%s/1.000.000\|25,20\|10.15\|200/\=submatch(0) + 10/g
output: 11 35 20 210
What I expected: 1.000.010 35,20 (or 35) -- 210

%s/1.000.000\|25,20\|10.15\|200/\=submatch(0) + 1.000/g
output: 2.0 26.0 11.0 201.0
What I expected: 1.001.000 1025 - 1.200

%s/1.000.000\|25,20\|10.15\|200/\=str2float(submatch(0)) + 10,0/g
output: invalid expression
What I expected: 1.000.010,0 35,20 -- 210,0

%s/1.000.000\|25,20\|10.15\|200/\=str2float(submatch(0)) + 1.000/g
output: 2.0 26.0 11.15 201.0
What I expected: 1.001.000 1025,20 -- 1.200
