Evaluating numbers and characters with M-: prints their value and
additionally to that the octal, hexadecimal and character representation
of the number if it's printable. I've checked its docstring and was
surprised to read that the aforementioned behaviour should only happen
when using a prefix argument of zero. This either means that the
docstring should be updated to make clear that this behaviour also
happens when using without any kind of prefix argument or the function
should be changed to not display this information when used without any
prefix argument.
The same question applies to other functions making use of the internal
`eval-expression-print-format' function that is responsible for
returning the alternate representation of the number, such as
`eval-defun-2' and `eval-last-sexp-print-value' in lisp-mode.el and a
few more.

It seems to be fixed on the master branch.
I just tried :
"M-: 5 7 RET" show "57" in the echo area
"C-u M-: 5 7 RET" inserts "57" in the buffer
"M-0 M-: 5 7 RET" inserts "57 (#o71, #x39, ?9)" in the buffer
But indeed I observe the same problem on emacs-24.

Not for me.

"M-: 5 7 RET" displays "57 (#o71, #x39, ?9) in the echo area.
"C-u M-: 5 7 RET" inserts "57" in the buffer.
"M-0 M-: 5 7 RET" inserts "57 (#o71, #x39, ?9)" in the buffer.
The first seems wrong to me or at the very least underspecified. The
others are as I'd expect them to be from the documentation.

Indeed, I was wrong, sorry. I don't know what was intended, but I guess
it's a docbug.

Yes, we should fix the documentation. The code was working like since
longer than I can remember.

I fixed it in 06952353 "Fix docstring of eval-expression".
