Technically you are right, but I am after a string which I can just cut off at some point and insert a decimal dot, so I am flexible.

The point of the exercise is for _printing_, into LaTeX. That is, I want to generate output like `raw"$4.92 \cdot 10^{-3}$"` and `raw"$22.71 \cdot 10^{6}$"` (engineering notation).
