Format ~E nit -- language lawyer sought
What should be the result of (format nil "~E" 1.0)?
C. All of the above
D. None of the above
The top of page 393 says, "Next, either a plus or a minus sign is
printed, followed by e digits ... [decimal exponent]"
Later on page 393 we see, "If all of w, d, and e are omitted, then the
effect is ... [like prin1].
Page 366 [presumably where prin1 is defined] doesn't explicitly say that
the plus sign is omitted from the exponent, but all the examples (and
usual practice) indicate that.
The first reference implies that A is correct, the third reference
implies that B is correct. The second reference implies that A and B
are the same.
