void floats (void) {
  cl_object vector;
  vector = cl_vector(2, ecl_make_singlefloat(1234567890123456.0),
                        ecl_make_doublefloat(1234567890123456.0));
  cl_print(1, vector);
  cl_terpri(0);
}

If you've installed ECL into /usr/local , you can look through the
headers in /usr/local/include/ecl/ [the way I did to answer your
question].
