We know that the avg variable actually ends up holding a 32 bit quantity, since it's an average of such numbers. It is only a u64 because it is temporarily used to hold the sum. Making it an actual u32 allows gcc to generate slightly better code, e.g. when computing the square, it can do a 32x32->64 multiply.
