Hello,
I'm trying to look up Metric Prefixes using their abbreviations. However,
the lookup needs to be case sensitive to distinguish between, for example,
"E" for exa and "e" for dekao or "M" for mega and "m" for milli.
I would suspect that there is a way to do this using the Exact Function in
conjunction with a lookup function, but I can't seem to get anything to work.
I did manage to get a working function by adding a helper column with the
Ascii code, then doing the match on that column, but if there's a way to do
it without the helper, I'd love to see how.

If anyone has any ideas, please let me know.

Thanks.
