<span>I found the following about exponential notation at this site:
http://www.vendian.org/envelope/dir0/exponential_notation.html
"Exponential notation lets you move the decimal point in a number. It
simplifies numbers by getting rid of zeros, and making math easier. Getting
rid of zeros helps with big 100,000,000 and small 0.000,000,001 numbers.
