hubFS: THE place for F#

Hi

I am a newbie with F# and has been creating a function which calculates power of n for any integer. I wanted to result to hold very large values like 5^5000.

I created following function  for the same


open Microsoft.FSharp.Math.BigInt

let rec Power (x:bigint) (y:bigint)   =  if y=of_int 1 then x else  x* Power of_int x of_int y-1

However, when compiled i am getting following error.

Error    1    This value is not a function and cannot be applied  
Error    2    This value is not a function and cannot be applied  

I have "bolded" the place where the error is  being shown.

If i put a braces around the arguements of power, i am getting following error.
Error    1    Expecting a type supporting the operator '*' but given a function type. Are you missing an argument to a function?   


Can any one please guide me ?? Also can anyone please tell how i can accept parameters as int and return as bigint ??

Thanks n Regards

Perhaps you need to write something like that
  let rec Power (x:bigint) (y:bigint)   =  if y=of_int 1 then x else  x* Power (x) (y-of_int 1)
and use it as
   Power (of_int 120) (of_int 10)
