Yes; that's the primary motivation for 64-bit architectures. But good luck buying a machine with 2^64 words of memory (real or virtual) .... though an machine with 8-32 GB of RAM isn't such a bad thing to have.
Note also that in J64, integers have widened to 64 bits, so they can hold much larger magnitudes without overflowing to floats. That's really useful, for example, for encoding information compactly using large-radix numbers. -Dan Please excuse typos; sent from a phone. > On Jun 12, 2014, at 9:05 AM, Björn Helgason <[email protected]> wrote: > > A process has a 4GB virtual address space (VAS); each address > from 0 to 2^32 can have a byte value. > > Is this 2^64 in 64 bit? > ---------------------------------------------------------------------- > For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
