I had to rewrite this, it was a typical confusion on my system where I work with both . and , as digital separator.
with 4 digits there is no . as a thousand divider
1234 > 1234
12345 > 12.345
123456 > 123.456
1234567 > 1,23457e+06
Yes. In all my experience this is standard. Generally, it’s expected that a divider will not be used when dealing with numerals denoting quantities less than ten thousand.
