The "discrete" and "continuous" data types make some sense.
Still, I have an issue with this division: in mathematics "continuous"
and "discrete" terms have a different meaning: real numbers are
considered continuous, whole numbers are considered discrete. But both
real and whole numbers can be classified into ranges, even though only
real numbers are really continuous :-)
