I've found several printing bugs in the format chapter.
1) The code on p. 394 to show the scale factor doesn't work. It
should be something like:
(dotimes (k 13)
(format t "~%Scale factor ~2D:~:* |~13,6,2,VE|"
(- k 5) 3.14159))
Ie, Missing % at the beginning and a missing ~:* to back up to the
scale factor again (or add (- k 5) as a third arg in the second
position and don't include the ~:*).
You are quite right.
2) The output to this code with scale factor of 7 is missing a 0 after
the decimal point. Ie. |3141590.0E-06|, not | 3141590.E-06|.
I disagree. In this case k=7 and d=6. Page 392 specifies that there will
be k (7) digits before the decimal point and d-k+1 (0) digits after the
decimal point. The requirement on page 393, that a zero digit should
appear after the decimal point if permitted by the width constraint,
applies only in the case that the parameter d is omitted.
3) The format expr in the function definition of FOO (on p 396) is
missing a 4th x arg.
Right.
