Some books deploy () for matrices too, however [] is more frequent. Though for sequences, pairs, tuples etc it is almost always (). So Ada 83 was pretty much consistent with mathematical notation in aggregates too. BTW, in mathematics [x] or |_x_| denotes real number truncation. -- Regards, Dmitry A.
