looks like an exponential notation ... the zero prior to the five, "05", looks strange.

5E-5 is scientific notation for $5 \times 10^{-5}$ on my calculator.

Where did this notation come from?

That is true.
That means "e" refers to base 10.
Zero prior to five is ok, because the scale has divisions marked 05 ,15, 25,35,......etc.

Thanks for help

n It is more common to use 'E" rather than "e" for this notation, to avoid confusion with Euler's constant.
