only if there is a truncate or floor -Inf function builtin, otherwise you have to implement it yourself requesting changing scale nilly willy at top level isn't good because it affects all expressions if there were an inversion of behaviour with C: bc: b ^ trunc(e) /* easy to avoid warning */ C: cast_assignment_to_bool = 1 if (x = y) statement; /* not easy to avoid warning */ cast_assignment_to_bool = 0 well, except that the bc workaround requires more work than the fictional braindead substitute for wrapping C assignments in parenthesis
