Perhaps this discussion could morph into a wiki-page which describes cosmetics of numbers, numerals, and scientific notation (which is a far-cry from numerology ;-)).

For instance, I might like to display a dollars-and-cents value as $12.70 rather than $12.7 but can accept $12.7 for now while I focus on higher-level stuff to present to my students.  (I do not want "BEST" to be enemy of "GOOD".)

PS: thanks Arnie and Brian for reference and code-fragments.
