Cool. I need to browse through the dictionary. Maybe I need an app
like one of those word-a-day vocabulary builders.
However, there are interesting things that can sneak through as in
"3e0" (exponent notation, similar to scientific
"10.00" (zero fraction)
"1000000000000000000.888" (big number)
Of course, there may be times when one wants to allow those integers.
