I would love to hear why that's wrong, when we use whitespace to separate pretty much everything in textual representation.

Well, SI did standardize the thousands separator as space, so there is at least precedence for using spaced numbers there.

I personally don't like it though, and tend to prefer either the swiss system (ie, 3'800'000.0), or maritime system (ie 3_800_000.0) if separators must be used
