Re: [Jbeta] Floating %. goes very bad very fast (mea culpa)
I don't expect floating answers to be exact. However, most of my use of computers begins with inexact numbers, so getting the floating routines as good as possible seems like a worthy effort to me. Unfortunately, I stopped my reseach when J's answers went very wrong at H 9. Nars also supports extended percision and rational numbers, so I've continued the work. While it does well though 12, it goes horribly wrong at 13. http://home.comcast.net/~paul.l.jackson/PLJsAPL/JandNars.txt Paul On Mon, Jun 18, 2012 at 7:01 PM, Roger Hui rogerhui.can...@gmail.com wrote: Don't you become even a bit suspicious when the answers don't agree?

Yes, 1!:1[1 hangs the same way. I should say that both worked on Android until version 1.0.5, although I hadn't used keyboard input until you suggested it.

There are 3 cases in J where the J interpreter calls for input from 'up the stack'. The simplest is 1!:1[1 and you can test to see if that hangs the same way. The other cases are : keyboard input and debug suspension. This is one of the harder problems to solve for each platform. I'm sure this will be sorted out eventually.
