Hi Dominic,

I am trying to compute the sum i = 0 to n where n = 1000 of n^n, but
chicken seems to return the incorrect answer.

Racket and scheme48 both seem to give different answers too.

Oddly enough, when I run your code (both versions), I get the same answer as you did for Racket.  Also, the Ruby program below agrees with *my* Chicken answer (and your Racket answer). (My computer here is a bit behind the times - this is on Chicken 4.6.2)

sum = 0
1.upto(1000) do |i|
  sum += (i ** i)
end

puts sum

  cheers,
