Ackermann Function

[Kernelpanic]

I've been experimenting a bit, and I think I've come across an interesting point: the variable types.

The screenshot is practically self-explanatory. 
It is fastest if one declare the type with _Unsigned Integer in the declaration and in the function itself: 76.922 seconds.
In both Long is the slowest: 90.711 seconds, and Long in the declaration and _Unsigned Integer in the function, is in the middle: 80,219 seconds.

PS: And so, some more tenths of a second less: 76.484  

Code: (Select All)

Declare Function ackermann(m as _Unsigned Integer, n as _Unsigned Integer) as _Unsigned Integer
