i'm sorry, another one popped up and I hope you can help me with it
it's with this example
class Plotlight
def fib n
if n<2
n
else
res = fib(n-2)+fib(n-1)
end
end
end
when executing, I get Object must be of type String. I suspect this to
be because I am feeding it a String argument. When I do this
class Plotlight
def fib arg
n = arg.to_i
if n<2
n
else
res = fib(n-2)+fib(n-1)
end
end
end
it now says
+ $exception {"undefined method `to_i' for 12:ClrString"}
System.Exception {System.MissingMethodException}
so it again must be because it's not an expected Integer...but how do I
work around this one? I am trying to understand how this works.
Thanks
Marco
