-# isnum returns True if its argument is a valid number,
-# and False (retval=1) if it is any other string.
-# The first pattern requires a digit before the decimal
-# point, and the second after the decimal point.

-# BASH NOTE: make sure you have executed `shopt -s extglob' before
-# trying to use this function, or it will not work
