e+ is such an unintuitive decimal representation system. going in blindly, it's completely non-obvious what "e" stands for, surely "d" would make far more sense. also, the namespace for e is plenty filled up as is, and, most of all, +12 implies 12 additional digits, not digits after the point

Google's choice to use it for calculation results despite having essentially no restriction on text space always annoyed me. I think this is the first time I've seen a human using it

The use of E notation for scientific notation dates back to 1956: https://en.wikipedia.org/wiki/Scientific_notation#:~:text=wh...

It’s also pretty common on scientific and graphing calculators; the first time I saw it was in junior school in maths.
