Method fuzzyCompare

output/java_guava/1.4.18/DoubleMath.java:379–389

Compares a and b "fuzzily," with a tolerance for nearly-equal values. This method is equivalent to fuzzyEquals(a, b, tolerance) ? 0 : Double.compare(a, b). In particular, like Double#compare(double, double), it treats all NaN values as equal and greater than all o

(double a, double b, double tolerance)

  public static int fuzzyCompare(double a, double b, double tolerance) {
    if (fuzzyEquals(a, b, tolerance)) {
      return 0;
    } else if (a < b) {
      return -1;
    } else if (a > b) {
      return 1;
    } else {
      return Booleans.compare(Double.isNaN(a), Double.isNaN(b));
    }
  }
