This depends on your system settings and Excel settings.
If your system uses comma as decimal separator (for example, one-and-a-half is written as 1,5), then you need to use a semicolon between the arguments of a function.
If your system uses point (dot, period) as decimal separator (for example, one-and-a-half is written as 1.5), then you need to use a comma between the arguments of a function.
You can specify this in the regional settings of your computer.
In the desktop version of Excel for Windows, it is possible to customize the setting for Excel only. If your system uses comma as decimal separator, but you want to use point in Excel:
- In Excel, select File > Options.
- Select Advanced.
- Clear the check box 'Use system separators'.
- Enter a point in the 'Decimal separator' box.
- Enter a comma in the 'Thousands separator' box.
- Click OK.
