! #X text 478 252 Below is a brief explanation of each of these logical

! #X text 473 53 These objects are adopted from the mother of all object

! and shift operations on 32-bit numbers.;
! #X text 467 100 WHAT DOES "BITWISE" MEAN?;
! #X text 478 208 Hence \, performing "bitwise" relational tests means
! that PD can compare "1101" to "1001" instead of operating with the
! integers that are represented by those binary codes.;
