E.g. 3000,000+-10,000 can be written as 300e4, while 3000,000+-0 must be written as 3000,000.

In theory, yes. In practice, we have tons of values in the DB which are +-0 but only because nobody bothered to set the proper precision. In fact, I think most of the people have very vague idea about how that works. Also, given the current UI, it's kind of hard to set the correct one. If you are dealing with something like US GDP, we have 17,419,000,000,000 as a value, and it has +-1 as precision, which is clearly absolutely wrong, nobody knows it up to a dollar. But to make it right, one needs to type 1000000000 (my guess about the actual precision) without making a mistake in the count of zeroes. And do it consistently for every GDP figure. The odds of that happening on Wikidata seem very low to me.

OTOH, I would very much appreciate seeing the number above as 17.419 trln or 17,419 bln or at least 17.419×10⁹. It's much easier to consume than a huge row of zeroes.
