Millions, thousands and ...?

How do I ask to make it absolutely clear?

I'm not sure what you're asking. Do you mean that instead of EUR 10,000,000 you want to see EUR 10 or EUR 10m?

Or do you mean that instead of "10 million EUR", you want "EUR 10,000,000"?

"Please write the numbers in full." ?

It might help to give an example.

Please write amount in full numbers (or digits), for example "EUR 10,000,000".

If they are filling out a form or using a database, "please enter..." instead of "please write" might work better.

"Please show amounts to the nearest euro."

Just curious, but why don't you just multiply it yourself (unless, of course, the people providing the info round up when putting the # in millions or thousands).

Thanks for the phrases "write the numbers in full" and "show amounts to the nearest euro". They will be very useful in my future communication.

In this case, I'm really looking for a single word. Let me give you an example. Number 12,345,678 needs to be shown in an excel table like this:

Millions Thousands ???
12 345 678

What do I call the last column?

# 7: The spaces in my example of an excel table disappeared, and I realize it's not clear what I meant. Let me put it like this:

12,345,678 needs to be shown like this:

Millions: 12
Thousands: 345
???: 678

Oh, that's easy: 'Units'.
