Irv has captured the ''essence'' of what a data-type is; compared to:

wikipedia: "''This data type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored.'''

(I know this is true because I wrote this down a while back...)

The conventional view of operations, meaning, and storage do not apply.

An expression may compute to a real value; but you can't assign that value to an integer. Euphoria never constrained how you write an expression, what the result was, and what you can do with your result--only you better assign an integer to an integer variable.

A ""data-type"" in Euphoria/Phix is a different animal from a conventional beast.
