Hmmm... your question is ambiguous. Could you clarify what you mean?
(1) Do you want each numeric element to translate into a single boolean (e.g. all zeroes to false and everything else to true)?
---> In this case you could e.g. feed your array through a "not equal zero" node from the boolean palette.
(2) Do you want to create a 2D array with each column corresponding to the bits in each integer and each row corresponding to each integer or vice versa?
---> Feed it in an autoindexing FOR loop containing a "number to boolean array" node. The 2D boolean array will emerge on an autoidexing terminal on the right border.
(3) Are you thinking about something completely different?
