   Infinities and NaNs are not available on legacy systems that lack
-IEEE floating-point arithmetic.  On a circa 1980 VAX, for example, the
-Lisp reader approximates an infinity with the nearest finite value,
-and a NaN with some other non-numeric Lisp object that provokes an

+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.
 
 Here are read syntaxes for these special floating-point values:
