The values depend on whether you are running a 32 bit version of J or a 64 bit version of J. The largest integer in the 32 bit version of J would be the same whether you are running on a 32 bit or a 64 bit machine.
3!:n gives you information about the sizes of integers and floating point numbers. ----- Original Message ----- From: Henry Rich <[EMAIL PROTECTED]> Date: Wednesday, October 25, 2006 7:27 pm Subject: RE: [Jprogramming] Largest Integer > The smallest and largest integers can be found by > > (, 26 b.) _1 (32 b.) 1 > _2147483648 2147483647 > > The values depend on whether you are running a 32-bit or a > 64-bit machine. > > Henry Rich > > > -----Original Message----- > > From: [EMAIL PROTECTED] > > [EMAIL PROTECTED] On Behalf Of Leigh > > J.
