I know we have yet to organize a formal process for building and disseminating a community-driven implementation of J, but in anticipation of that day’s arrival, perhaps we can start collecting community-driven proposals for enhancements?
One such enhancement could be special code that detects whether the argument to an arithmetic dyad is the scalar _ (or __ or _.) and if so, avoids demoting the other argument to double if it’s already extended or rational. I have other ideas too. But maybe we should collect them on the Wiki? -Dan > On Feb 2, 2016, at 9:12 PM, Henry Rich <[email protected]> wrote: > > No, extendeds promote to float on mixed operations. > > Henry Rich > > On 2/2/2016 9:09 PM, 'Pascal Jasmin' via Programming wrote: >> 9223372036854736345 <. _ >> 9.22337e18 >> >> result is a double. <. double is the closest integer it can find. >> >> this seems like a problem though: >> >> >> 9223372036854736345x <. _ >> 9.22337e18 >> >> >> >> ----- Original Message ----- >> From: Henry Rich <[email protected]> >> To: Programming forum <[email protected]> >> Sent: Tuesday, February 2, 2016 9:05 PM >> Subject: [Jprogramming] When a <. _ is less than a >> >> I'm stepping up to the world of 64-bit integers, and stepping into cowflops. >> >> This took me quite a while: >> >> <. 9223372036854736345 <. _ >> >> 9223372036854735872 >> >> >> See that?
