Your analysis about the floating point value is of course correct.

The relevant code should instead be doing something like this:

{
  double x;
  double xi;
  int usec;
  x = 10.000001;

  xi = floor(x);
  usec = floor ((x-xi)*1000000);
  if (xi + (usec + 1) * 0.000001 <= x) {
    usec++;
  }

  printf("usec %d\n", usec);

  return 0;
}
