From other distances, the strokes gained or lost are typically fractional. For example, suppose a golfer one-putts from eight feet. The Tour average from that distance is 1.5, so a one-putt gains 0.5 strokes, but a two-putt loses 0.5 strokes.
It's very similar to the strokes gained putting stat; the number of strokes a player makes up on the field thanks to his putting. If the par is 72 and Rory McIlroy goes around in 65 with a strokes gained putting clip of 2, then his strokes gained tee to green stat for the round would be 5, meaning he gained those 5 strokes on the field from tee-to-green.
