Our example code calculates the total value transacted in this block is 10,322.07722534 BTC (inclusive of the 25 BTC reward and 0.0909 BTC in fees). Compare that to the amount reported by a block explorer site, by searching for the block hash or height. Some block explorers report the total value excluding the reward and excluding the fees. See if you can spot the difference. Our example code calculates the total value transacted in this block is 10,322.07722534 BTC (inclusive of the 25 BTC reward and 0.0909 BTC in fees).
