+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).
 
 If `eval-expression-debug-on-error' is non-nil, which is the default,
 this command arranges for all errors to enter the debugger."
