Normally, this function truncates long output according to the
value of the variables `eval-expression-print-length' and
`eval-expression-print-level'. With a prefix argument of zero,
however, there is no such truncation. Such a prefix argument
also causes integers to be printed in several additional formats
\(octal, hexadecimal, and character when the prefix argument is
-1 or the integer is `eval-expression-print-maximum-character' or
less).
however, there is no such truncation.
Integer values are printed in several formats (decimal, octal,
and hexadecimal). When the prefix argument is -1 or the value
doesn't exceed `eval-expression-print-maximum-character', an
integer value is also printed as a character of that codepoint.
If `eval-expression-debug-on-error' is non-nil, which is the default,
this command arranges for all errors to enter the debugger."
