just use the bitwise AND function (&) to determine if the correct bits are set.

Haven't been on for a while, but here goes (Sorry delta!)
If you push the hat up by your code then it will default to the first conditional statement you put in.

A more correct way might be to do it this way (using constants provided courtesy of Astronouth7303)

switch (px_wheel & 0xFC) {
	case Hat_Up_Left: {
		// ... Code here
		break;
	}
	case Hat_Up_Right: {
		// ... Code here
		break;
	}
	// etc...
	default: {
		break;
	}
}
