How do Europeans write a list of numbers with decimals?

Question

As I understand it, Europeans(*) write numbers with a comma for a decimal separator, so one-and-a-quarter is written as 1,25

Europeans also use commas to separate lists, so how do you write a list of decimal numbers? I, as an Englishman, would write one-and-a-quarter, one-and-a-half, one-and-three-quarters like this:

1.25, 1.5, 1.75

How do you do that in Europe?

(Why is this a programming question? Because I'm writing a program that will ask European users for a list of numbers!)

_{* For the purposes of this question, there are no English-speaking countries in Europe. :-)}

Answer 1

I'm European (french), and in almost all programs here we have to use semicolons ';' as a separator, even if the numbers are only integers because the comma doesn't look like a separator for us. In mathematics, semicolons are the only right way here to separate a list of numbers.

The most common example is when we have to enter the page numbers we want to print on a PDF, all programs ask for a semicolon-separated list and I clearly found it intuitive. I think they would have changed it if it was uncomfortable for some.
