Paul Graham, Ansi Common Lisp, p. 144, has
an example of applying float to a lisp list using
mapcar, but it doesn't seem to work for me
using maxima in lisp mode:
-------------------------------------
MAXIMA> (float 2/3)
0.66666666666666663
MAXIMA> (mapcar #'float '(1 2/3 .5))
Maxima encountered a Lisp error:
Error in FUNCTION [or a callee]: The function FLOAT is undefined.
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
MAXIMA> (to-maxima)
Returning to Maxima
(%o4) true
(%i5) (display2d:true,build_info());
