// numerical round-off errors. The input indices are considered the
// positive ordering. The output indices are either positively ordered
// (an even number of transpositions occurs during sorting) or negatively
// ordered (an odd number of transpositions occurs during sorting). The
// functions return 'true' for a positive ordering and 'false' for a
