Function: rhs (<expr>) Returns the right-hand side (that is, the second argument) of the expression <expr>, when the operator of <expr> is one of the relational operators < <= = # equal notequal >= >, one of the assignment operators := ::= : ::, or a user-defined binary infix operator, as declared by infix.

eqAirCon:

When <expr> is an atom or its operator is something other than the ones listed above, rhs returns 0.

See also lhs.

Examples:

          (%i1) e: aa + bb = cc;
          (%o1)                     bb + aa = cc
          (%i2) lhs (e);
          (%o2)                        bb + aa
          (%i3) rhs (e);
          (%o3)                          cc
          (%i4) [rhs (aa < bb), rhs (aa <= bb), rhs (aa >= bb),
                 rhs (aa > bb)];
          (%o4)                   [bb, bb, bb, bb]
          (%i5) [rhs (aa = bb), rhs (aa # bb), rhs (equal (aa, bb)),
                 rhs (notequal (aa, bb))];
          (%o5)                   [bb, bb, bb, bb]
          (%i6) e1: (foo(x) := 2*x);
          (%o6)                     foo(x) := 2 x
          (%i7) e2: (bar(y) ::= 3*y);
          (%o7)                    bar(y) ::= 3 y

          (%o8)                         x : y
          (%i9) e4: (x :: y);
          (%o9)                        x :: y
          (%i10) [rhs (e1), rhs (e2), rhs (e3), rhs (e4)];
          (%o10)                  [2 x, 3 y, y, y]
          (%i11) infix ("][");
