Hi list,
I have ported GNU APL to the OpenBSD operating system, and I kindly ask
you to consider the possibility of merging the following changes to the
source tree, in order to enable a better support for the OS. As you can
see, only few lines are needed.
Also, I recollected some info about the s
Hi Giuseppe,
thanks for submitting the patches. I have included them into SVN
1001.
The first patch is now in Makefile.am as opposed to configure.
That suggests that you
are using an older version of the GNU APL sources. Maybe the one

Hello all,

thanks, fixed in SVN 1002.

Hi Jürgen,
thanks for your reply.
Ported software on OpenBSD is submitted for inclusion in the so-called
"port tree", basically a set of custom Makefiles by means of which
ports can be automatically downloaded, built, packaged and installed
with a single "make" command. The port tree is part of the

Trying to reduce the steps above to 'define, save, define' gives the
same thing above. This only happens when the defined function is saved
without a body (saved only with the header).

Hello again,
Please ignore the previous email. I now see corrections were
made somewhere between svn 996 and 1003. My bad.

Hello,
Is there an existing mechanism for accessing rational number
numerator and denominator parts analogous to that for accessing complex
number real and imaginary parts? If yes, please let me know how. If
no, can a mechanism be implemented?
Respectfully,
Fred
Hi,
No APL kb with me right now, sorry :(
1 LCM n
gives the numerator of a fraction (floating or exact). If you need the
denominator, do the same with the inverse of n. If you need both, for example:
1 LCM n POW 1 _1
Cheers,
Louis

Louis,
Thanks for the quick response.
After working with the technique a bit, I observe that as long
as the rational number denominator is well within the range of integers
representable by floating numbers, 1 ∧ n returns the correct result.
But if the absolute value of the denomi
Perhaps it's time for a new release? Or should it be delayed until the
rational number support is stable enough to be default?

The true benefit of rational numbers is realised once there is support for
bigints. Jürgen has suggested that that is planned, and personally I can't
wait.

larger than ~62 bits or 920 ?
If so, I would agree 100%. Having a limit that is less than exact 64 bits
(signed or unsigned)
is wrong. encode & decode can't manage more than ~62-~63 bits limit.
my 2 cents,
Xtian.
