if [[ "$result" == *.* ]]; then
# improve the output for decimal numbers

Google Calendar Improved
/* GOOGLE CALENDAR Improved
You use google calendar right? Try this for fun (it is really quick):
open google chrome,
type command-Shift-C,
hit escape twice to see the console,
then paste this whole message in
and hit enter:
You can then hit command-shit-i to remove the console....
Just refresh if you don't like it... and it will go away. */
