Interesting, 4o got this right for me in a couple different framings including the simple "Which number is larger, 9.9 or 9.11?". To be a full apologist, there are a few different places (a lot of software versioning as one) where 9.11 is essentially the bigger number so it may be an ambiguous question without context anyway.

How can "which is the larger number" be an ambiguous question?

Which is the bigger version number? Version 9.9 or version 9.11? Which is the bigger dollar amount? $9.9 or $9.11?

Periods are not always used for the decimal separator but also as a separator for multiple sets of semi-independent numbers.

As everyone else has said, semver. I use semver so often that my initial reading of 9.9 < 9.11 in a Hacker News comment would evaluate to true.

There are some contexts where 9.11 is larger than 9.9, such as semver, so it could be ambiguous depending on the context.

Larger in magnitude or in count of digits?
