I'm glad that the Coyotes have something useful to do, besides keeping
me awake
all night in the Anza Borrego desert (it was wonderful to hear them
all night actually!)

But my question is more pointed:
if you assign x=3.3
and you know apriori that the floating point data type
will not have enough bits to store this number precisely,
why does "print" show this number as 3.3?

Is it because it is rounding off with some kind of algorithm?
Or am I misinterpreting how this number is being stored?

Curious,
Elisha
