It should also be pointed out that Java in fact does the same thing:
$ cat Test.java
class Test
{
public static void main(String[] argv)
{
double i = -50.0;
for (int x = 0; x < 5; x++)
{
i += 0.1;
double z = i * 10.0;
System.out.println("");
System.out.println(z);
System.out.println((int) z);
}
}
}
$ javac Test.java
$ java Test
-499.0
-499
-498.0
-498
-496.99999999999994
-496
-495.99999999999994
-495
-494.99999999999994
-494
