This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.2 (beta31) "Iris" [Lucid] (i686-pc-linux, Mule) of Fri Mar 10 2000 on kei.cwru.edu configured using `configure --with-mule' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: The expression (string-to-number "1e1" 16) returns the value 10.0. I think this should be 481. Thank you. Sincerely, Keisuke Nishida
