WARNING: Numerical operation combines exact and inexact
numbers (rational
numbers and floating-point numbers), and the
mathematical result is
exact. See ANSI CL 12.1.4.1 and the CLISP
impnotes for details. The
result's actual exactness is controlled by
*FLOATING-POINT-RATIONAL-CONTAGION-ANSI*. To
shut off this warning,
set
*WARN-ON-FLOATING-POINT-RATIONAL-CONTAGION* to NIL.

WARNING: Floating point operation combines numbers of
different precision. See

the fix is to insert R_F_float_F calls at the
appropriate places, but one has to be careful because
there are lots of such places.
