These are functions for converting integers into bit vectors and back. bitvec(A,S) converts (the least significant S bits of) a positive integer to an S-bit vector and dbitvec(A,S) takes an S-bit vector A and returns an integer. The usefulness of these is that bitwise logic operations can be performed using Mathcads vectorise operator - on AND in the example. This is in Mathcad 15 format
