ZeroMath ArrayMultiply

[Luc-Sol]

This modifies the original array, is this something we want? Or should it return a new object? Not being aware of the difference has caused some bugs occasionally, so whatever choice we make it should be made more clear with either a better name or better documentation.

I think I would prefer it to not modify the original.

And if we would need a function that just modifys the original array, just make it return nothing (void), to not cause confusion.
