change method name 'round_with_zero' to 'round_for_report'.
use round_for_report instead of round() in order to correct -0.0 to 0.0.
Fix: after shift to round_for_report, the output should be convert from string to float for score comparison.
use round_for_report instead of round() in order to correct -0.0 to 0.0.
in order to be the same with Hologic report, should correct -0.0 to 0.0.
