Michael McCandless commented on LUCENE-7194: -------------------------------------------- Thanks [~daddywri]. I think we should just add this to our forbidden API list, then see what fails (because it's using these APIs), and correct them... > Ban Math.toRadians/toDegrees and remove all usages of it > -------------------------------------------------------- > > Key: LUCENE-7194 > URL: https://issues.apache.org/jira/browse/LUCENE-7194 > Project: Lucene - Core > Issue Type: Bug > Reporter: Robert Muir > Assignee: Karl Wright > > The result of these methods is unreliable and changes across jvm versions: we > cannot use these methods. > The following program prints 0.7722082215479366 on previous versions of java > but 0.7722082215479367 on java 9 because Math.toRadians is no longer doing > the same thing: > {code} > public class test { > public static void main(String args[]) throws Exception { > System.out.println(Math.toRadians(44.244272)); > } > } > {code} > This is because of https://bugs.openjdk.java.net/browse/JDK-4477961. > I am not really sure its a bug, because the method says that the conversion > is "generally inexact". -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
