Attached is a patch which implements the above feature. I was a
surprised to find that negative integers don't wrap around in C as
they do in Ruby:
C:
-4 % 4 => 0
-3 % 4 => -3
-2 % 4 => -2
-1 % 4 => -1
0 % 4 => 0
1 % 4 => 1
2 % 4 => 2
3 % 4 => 3
4 % 4 => 0
Ruby:
-4 % 4 => 0
-3 % 4 => 1
-2 % 4 => 2
-1 % 4 => 3
0 % 4 => 0
1 % 4 => 1
2 % 4 => 2
3 % 4 => 3
4 % 4 => 0
