Description Severin Gehwolf 2018-09-19 16:31:10 UTC
Description of problem:
Similar to bug 1628612. It produces -710.989276736877 instead of -744.4400719213812 as a result.

Version-Release number of selected component (if applicable):
$ rpm -q java-11-openjdk
java-11-openjdk-11.0.ea.28-5.fc28.aarch64

How reproducible:
100%

Steps to Reproduce:
$ cat TestMath.java 
public class TestMath {
	public static void main(String[] args) {
		int testfail = 0;
		double expected = 0.7833030468809974;
		double res = Math.cos(1647100);
		if (res != expected) {
			System.out.println("Test Math.cos() FAILED! Got: " + res + " instead of " + expected);
			testfail++;
		}
	        double x = 4.9E-324; 
		res = Math.log(x);
		expected = -744.4400719213812;
		if (res != expected) {
			System.out.println("Test Math.log() FAILED! Got: " + res + " instead of " + expected);
			testfail++;
		}
	        if (testfail > 0) {
			System.out.println("Test FAILED! Got " + testfail + " failures.");
		} else {
			System.out.println("Test(s) passed!");
		}
	}
}
$ javac TestMath.java
$ /usr/lib/jvm/java-11-openjdk/bin/java TestMath
Test Math.log() FAILED! Got: -710.989276736877 instead of -744.4400719213812
Test FAILED! Got 1 failures.

Actual results:
Test Math.log() FAILED! Got: -710.989276736877 instead of -744.4400719213812
Test FAILED! Got 1 failures.

Expected results:

Comment 2 Severin Gehwolf 2018-09-21 08:07:05 UTC
With a build including the fix from the PR I see this:

<mock-chroot> sh-4.4# rpm -qf /usr/lib/jvm/java-11-openjdk/bin/java
java-11-openjdk-headless-11.0.ea.28-6.fc30.aarch64
<mock-chroot> sh-4.4# /usr/lib/jvm/java-11-openjdk/bin/java TestMath
Test(s) passed!

I'm going to merge it in.
