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

`eval-expression-print-length' and `eval-expression-print-level',

on the length and level of lists, and include additional formats
for integers (octal, hexadecimal, and character)."
