Nope it is 4.

Just had to prove that I was a human to send off a submission on a
website and that was their question and answer.

Anyone else agree that the answer is four and not 4?

Don't ask whisky-dave, he'll come up with anything but 4 (four)! ;-)

I would say that the only time it would make a tangible difference to
the answer / situation of using the numeral or the spelled version
would be down to specific rules or expectations?

Like on a cheque, you would write the numerals in the box and write it
out in full on the line as a means of a security checksum. Doing it
the other way round would probably get the cheque rejected (even
though you might be able to write a cheque out on plain paper)?

Also if there was a scenario that was using the numeric form then the
required answer might need to reflect that, or if in more of a written
form then to use the words?

If you want it to be very clear, you might write both, say on a legal
document (where both versions have equal validity)?

If you were selling a car, I'm not sure you would write the cost out
in words. If you were composing a receipt for the same you might use
both forms (if it was a high enough value)?

In your particular case, it may just have been that the syntax checker
was only looking for the numeric version, rather than it being 'wrong'
as such, like telephone number dialogue boxes that consider a space as
an additional and non valid number (or number of digits etc).

I was installing Raspbian (Debian Linux for the Raspberry Pi) the
other day and a step offered a Y/n input, where I believe the upper
case value reflects the default (should you just press Enter etc)? I
can't remember normally having to bother actually using an upper case
Y previously but in this case I did?
