Hi, So in for a particular speed and number of bytes are we meant to round up or just truncate the decimal places? For the final % time I've encountered no problems with just truncating the decimal positions but with the IO, if: The number of Bytes is 200B the speed is 3000000Bps, the current sample solution treats it at 67, but my code treats it as 66, as the actual time would be 66.666... I've attached an example of of this from the sample sol. What should be done here?
