A number calculated by adding together the number of games won and half of the number of games drawn, (ignoring the losses) then dividing that total by the total number of games that were played. Another way of calculating the winning percentage is by taking the percentage of games won by a player plus half the percentage of drawn games. Thus, if out of 100 games a player wins 40 percent, draws 32 percent, and loses 28 percent, the winning percentage is 40 plus half of 32, i.e. 56 percent.
