Infinities and NaNs are not available on legacy systems that lack
IEEE floating-point arithmetic. On a circa 1980 VAX, for example,
Lisp reads @samp{1.0e+INF} as a large but finite floating-point number,
and @samp{0.0e+NaN} as some other non-numeric Lisp object that provokes an
error if used numerically.
