Did anyone notice a behavior which differs from JDK for SunOS 5?
This maybe a bug of FreeBSD port of JDK.
=====
class inttest {
static public void main(String s[]) {
long a, b;
a = -1111123;
b = -1123;
System.out.println(a % b);
System.out.println(b % a);
a = 11123;
b = -123;
System.out.println(a % b);
System.out.println(b % a);
a = -1111123;
b = 1123;
System.out.println(a % b);
System.out.println(b % a);
}
}
=====
We'll see on SunOS 5 and Linux:
-476
-1123
53
-123
-476
1123
But on FreeBSD and JDK 1.1.6 V98-9-23:
476
1123
-53
-123
-476
-1123
