Hi all,

I am trying to implement a function that finds the significant figure of a 
number to a specified point i.e. 2.55555 3 = 2.556. I have implemented 
something like:

sig :: (RealFrac a, Integral b) => a -> Int -> a
sig x y = round y

However this doesn't work. Moreover at the Prelude when i type round 2.3333 
2 i get an error.
Any suggestions?
