Comparing those two values shall result in a \"true\":

53.9173333333333  53.9173

Answer 1

Apache commons has this: org.apache.commons.math3.util.Precision equals(double x, double y, double eps)

epsilon would be the distance you would allow. Looks like yours would be 1e-5?

The source-code of this method looks like it uses Math.abs as suggested in other answers.
