Subject: bug#5114: 23.1.50; (string-to-number (number-to-string most-positive-fixnum))
Date: Thu, 03 Dec 2009 15:36:27 +0100 [thread overview]
Message-ID: <m28wdkgm50.fsf@gmail.com> (raw)
(setq x (string-to-number (number-to-string most-positive-fixnum)))
(= most-positive-fixnum x) => nil
x is 2305843009213693440 but it should be most-positive-fixnum
which is 2305843009213693951.
The test
(= most-positive-fixnum
(string-to-number (number-to-string most-positive-fixnum)))
seems to work as expected on 32-bit machines but not so on 64 bit.
Helmut.
