As it turns out this was a CS class exercise in using sed and regex.
And excuse me, but you ARE using regular expressions in your example...

you don't need regex:
sed \
-e '/^ *$/d' \
-e 's/,/ \& $/' \
-e 's/\./,/g' \
-e 's/e/ \\cdot 10^{/' -e s'/$/}$\\\\/' \
/path/to/input/file
now, the exercice is to read the input file directly with LaTeX using
TeX macros instead of converting it.
