Strange that D is printing large values as zero. Any mistake in my code?

Those are all int (32 bit) literals so it is prolly wrapping 
around the intermediates before it actually assigns to DIM.

If you used 1024L it should be better, by making the right hand 
side 64 bit too.

It is similar to

float x = 1 / 2; // x == 0 because the right hand side is done as 
ints

float x = 1.0 / 2; // now x == 0.5
