I'm a mathematician, albeit not a numerical analyst, and I don't think
considering a float as the interval of real numbers to which it is the
closest floating point approximation is a particularly helpful point
of view.

Floats are perfectly normal rational numbers; it's the *operations*
which are weird.


 The rapid establishment of social ties, even of a fleeting nature,
 advance not only that goal but its standing in the uberconscious
 mesh of communal psychic, subjective, and algorithmic interbeing.
 But I fear I'm restating the obvious.  -- Will Ware, comp.lang.python
