Package: openjdk-7-jre
Version: 7~u3-2.1.1-1
Severity: normal
The Math methods sin(), cos(), and tan() are returning completely
incorrect values for large-ish input values. For example,
public class Weird {
public static void main(String[] args) {
System.out.println(Math.sin(10000000));
System.out.println(Math.cos(10000000));
System.out.println(Math.tan(10000000));
}
}
The output *should* be,
0.420547826145
-0.907270382175
-0.463530866219
But instead it outputs,
-0.7210329846302568
-0.6929007396988287
1.040600685379057
Other Math methods are likely affected as well, but I only tested
these three. In contrast, openjdk-6-jre is producing the correct
results.
