string to double conversion results in questionable precision
-------------------------------------------------------------
Key: QPID-2766
URL: https://issues.apache.org/jira/browse/QPID-2766
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: 0.6
Reporter: Rajith Attapattu
Assignee: Rajith Attapattu
Priority: Minor
Fix For: 0.7
The following test:
public void testString2Double_1() {
try {
Message message = senderSession.createMessage();
message.setStringProperty("pi", "3.14159");
assertEquals(3.14159, message.getDoubleProperty("pi"),0);
} catch (JMSException e) {
fail(e);
}
}
Fails with:
junit.framework.AssertionFailedError: expected:<3.14159> but
was:<3.141590118408203>
This appears to be because the client ends up doing the equivalent of
Double.valueOf(Float.valueOf(value)) when doing string to double conversion
rather than the more direct Double.valueOf(value).
