WebFor those of use who've been around long enough, the 64-bit transition has some parallels with the 16-bit to 32-bit transition of the mid-80s. There were computers that were IL32 and others that were L32 (adapting the new notation to the old problem). Sometimes 'int' was 16-bit, sometimes 32-bit. – Jonathan Leffler Dec 22, 2008 at 16:39 5 WebJul 5, 2012 · Unfortunately the shift operator does not apply to Int64.
