Hallo!
I would like to know how big an "UArray (100,100) Double" is (approximately) in Bytes.
I guess you mean: (accumArray const 0.0 ((1, 1), (100, 100)) []) :: UArray (Int, Int) Double It should take about 100 * 100 * 8 = 80000 bytes .
And how much heap will the program consume for it. (I mean does the garbage collector need this size, or double the size, or what?)
About the same. I just checked that GHC allocates it as a big object, so the array isn't copied during GC. Best regards Tomasz
