Challenge for you...

you need an exit condition, something like this

Code: (Select All)

function fak(n::Int)
      if n==0
              return 1
      else
              return n*fak(n-1)
      end
end

or if you want big factorial

Code: (Select All)

function fak(n::Int)
       if n==0
              return BigInt(1)
       else
              return n*fak(n-1)
       end
end

you could also use BigFloat instead of BigInt

Code: (Select All)

function fak(n::Int)
    f::BigFloat=1
    if n==0
        return f
    else
        for i::Int=1:n
            f*=i
        end
    end
    return f
end

fak(1000000)
