"cacra li revo .a li pare" "It lasts for 12 or 24 hours."

I suggest using the same order for the numbers in Lojban and in English.

".i mi citka renono mikrygrake be le xukmi" "I ate 200 µg of the chemical."

Shouldn't the place structure of "mikrygrake" be "x1 is x2 micrograms by standard x3"?

"Number strings are in base 10 (ten), unless overridden grammatically."

We can say that numbers are usually in base 10, and that there are means to specify otherwise, but what any number string represents in any given context does not seem to be something that can be dictated by the BPFK.

For example, say you are given the list of numbers: 12F3, AAC5, FFFF, 3312, B122. Are you really going to interpret "3312" as a decimal number?

Okay.

You are absolutely right.

I removed the example.

Suppose that "3312" came in isolation. Would one really interpret it as anything but a decimal number?

Perhaps I am living under the delusion that mathematical expressions, if nothing else, should be unambiguous. I have a profound sense of repulsion at the idea of not being able to, mechanically, determine if a string of digits refer to 3312 or 13074.

Number strings are in base 10 (ten), unless overridden grammatically. Context may, of course, override this default, but you risk being misunderstood if you rely on context in this fashion.

In complete isolation, it's just a string of symbols. If we know that it's a number, then yes, decimal would be the obvious first guess.

In general or in Lojban? In general mathematical expressions are not context independent. It's hard to see how the fact that one is using Lojban could change that. Given a mathematical expression, it can normally be read in any language.

The string "3312" could ba a postal code, a house number, and many other things. Without any context we can't really tell that it's a decimal number.

Since both of you appear to want to keep the context-dependence, I'll put it back in.

The best thing would be to have *both* context-independence, and sane behaviour with lists of digit strings. One way to do that would be to use a sticky base flag. Is that a bad idea?

If you mean something like {ki} but for numbers instead of tenses, I think it's a good idea.
