Exponential notation with significant figures.

"Scientific notation"

- is exponential notation,
- but leaves the decimal in a standard place

(After the first non-zero digit (ie, one can have 1. or 2. or 3. or 9. , but never 12. or 0.1))

- and then uses zeros to indicate significant figures.

The less restrictive exponential notation is more common
on the back of the envelope.

## Notes...

Caveat, caveat. Actually, the phrase "scientific notation" is rarely
heard outside of the classroom. "Exponential notation" seems to be
used to name both versions (both free-form and cannonicalized), with
only context indicating which is intended. If only to make teaching
simpler, I leave "scientific notation" its narrow meaning, and use
"exponential notation" as a strictly more general catagory.
There is probably an SI standard somewhere online which says what the
"right thing" is...

Perhaps move links to exp note page?
