Hi,
¯4○ is supposed to be equal to 5○¯6○. While trying to check this on GNU
APL, I noticed your ARCCOSH gives a domain error on my vector.
⎕IO←0
X←1D45*⍳8
8 1⍴¯6○X
DOMAIN ERROR

APL2 returns the answer. If I write my own ARCCOSH...

Hi,
I looked into the ¯4○ thing a bit more and have identified the discrepancy
between APL2 and GNU APL, which may or not be a bug depending on whether
the ISO spec agrees with APL2 on this function.
According to the APL2 language reference, if the real part is greater than
or equal to zero, or t

That changes the IBM result slightly, but the GNU APL one is still off by a
large amount.
