Re: How to convert a byte array ? Thanks for reply, Arno. As I mentioned above I need a 2D array as result because my flexgrid requires a 2D variant array for its LoadArray method. Let's say I would split further the byte array as below Code: myText = StrConv(myByteArray, vb...

The reason for using 0, however, is that it's supposedly more efficient, at least when using an ArrayList on HotSpot 8: .toArray(new MyClass[0]) or .toArray(new MyClass[myList.size()])? I'm not sure if it's more efficient in other versions, other JVM implementations, or for ...
binary_array = np.array([np.binary_repr(num) for num in int_array]) print(binary_array) In the code above, we first import the NumPy library as “np” to make it easier to reference in the subsequent code. Next, we create a NumPy array of integers using the np.array() function...
