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

Folks,

Are there any examples on using STUArray and friends? I'm trying to convert the following bit of code which uses deprecated features.

I don't understand the syntax needed to create a new double or float array with newArray from Data.Array.MArray.

do arr <- newArray_ (1,2) :: ST s (STUArray s Int Double) writeArray arr 1 d ... The type signature is to remove the ambiguity in type-class constraints.

I also don't yet understand how to cast that double array to read ints from it.

Don't. Best regards Tomasz
