Stocks can also be in fractional shares, thanks to things like stock
splits and "share-dividends".
Also, there can be need to deal with things like "4 pounds, 3 and a half
ounces"... now, are these avoirdupois pounds (U.S. "standard" for most
things, 16 ounces to the pound) or troy pounds (used for precious metals,
12 ounces to the pound)?
Hmmm... I don't recall anybody mentioning "time" as the unit of measure...
convert to seconds? minutes? hours? days? weeks? months? years?
I often deal with measurements in nanoseconds... many things get charged
for by unit time... e.g., phone calls, wages, room rents, ...
