Just a note on the use of e. Fifty years ago, when we programmed in Fortran, it would be written as 2.8EE-04

Many engineers and mathematicians used that, but in their personal notes, and on the blackboards, it was shortened to just one e (little e is easier to write than capital E), so 2.8e-4 would be the hand written version. It took and stayed, and many of us still use it. A few calculators use it also.
