OK.

Also allow multiplication/division, while you're at it:

  @@ -942,6 +942,7 @@ vcc_expr_mul(struct vcc *tl, struct expr **e, enum var_type fmt)
          case INT:       f2 = INT; break;
          case DURATION:  f2 = REAL; break;
          case BYTES:     f2 = REAL; break;
  +       case REAL:      f2 = REAL; break;
          default:
                  if (tl->t->tok != '*' && tl->t->tok != '/')
                          return;

(also add to the test-case).
