When a player crosses fifty runs, it is called a half century, and is recorded in the batsman's records. When a player crosses one hundred runs, it is a century, and is also recorded in the batsman's records.
But, to cross one hundred runs the player must have crossed fifty runs first.
What happens to the previous half century recorded, when the player completes a century as well?
Are they both recorded? Is the half century discarded and only the century recorded?
Similarly, what is the recording procedure when a player who scored a century goes on to score a double century?
