[Haskell-cafe] Examples of using STUArray + help with converting code

If I don't cast then how do I convert this code?

doubleToInts d = runST (
     do arr <- newDoubleArray (1,2)
        writeDoubleArray arr 1 d
        i1 <- readIntArray arr 1
        i2 <- readIntArray arr 2
        return (i1,i2))

Or can I just read an array of ints from the double array using the  
new polymorphic approach?

     Thanks, Joel
