Talk:Ackermann function

I don't really know how well my C++ function performs, as I said im just learning C++. but i though i would add it since there wasn't one. If something is wrong with it, please email me at ki4hbd(dot)nathan(at)gmail(dot)com and explain if you don't mind. Thanks!

Arbitrary precision with BC

BC is a binary calculator with arbitrary precision (similar to dc, but this one use the RPN, bc resembles C in its syntax); the code would be (translated from C):

#! /usr/bin/bc -q
define ack(m, n) {
   if ( m == 0 ) return (n+1);
   if ( n == 0 ) return (ack(m-1, 1));
   return (ack(m-1, ack(m, n-1)));
}

for(n=0; n<7; n++)
{
  for(m=0; m<4; m++)
  {
     print "A(", m, ",", n, ") = ", ack(m,n), "\n"; 
  }
}
quit

Would this be suitable for adding in the article? --ShinTakezou 14:05, 9 December 2008 (UTC)

You could also write bc examples for other articles in Category:Arbitrary precision. --IanOsgood 14:35, 28 December 2008 (UTC)

Comment preceding MUMPS code (moved from the page)

... when I told Tom Ackermann that this function existed, he couldn't believe that an actual mathematical function was named after a relative if his... May he rest in peace!

Abap results seem wrong

ZED version?

How do we read the ZED version? (What are we seeing there?) --Rdm 08:04, 3 August 2012 (UTC)

Java 8 example size

Could someone explain why the Java 8 version merits inclusion? It seems ridiculously long in comparison with the Java version above it. Does Java 8 require so much code? -Paddy3118 (talk) 17:38, 5 October 2013 (UTC)
