   ... clisp is _making an error_ ...

For the record, it is no error.  Lisp offers access to the
bare floating point hardware and CLISP keeps that promise.

PS: Rationals are there, the choice is yours.

PPS: Yes, I repeat up front what PJB said in the middle of a long message.

PPPS: I am curious, does anyone have a numeric "measurement" datatype
which preserves error information, e.g., value with accuracy,
increasing and decreasing precision as needed?
I've been expecting it in calculators
since the HP-35 but these days
I calculate rarely.

PPPPS: More elaborately, one might represent a measurement as a Gaussian
whose shape would likely become quite nightmarish
after only a few computations but
we have the cycles!
Perhaps such a proposal is best documented on the first of April?
