I just had a brief look at the code you posted. Are you not concerned about
accuracy in any of your calculations? Summing a 10 million element array by
simply accumulating each element into a running total is guaranteed to give
a lousy result.
Also, without running it I don't see how most of your Python examples work
since you seem to call the timing function with the result of the
calculation which doesn't make sense.
