Case contract

Score a skill-player stat line in integer hundredths. Passing yards earn 1 point per full 25 yards, rushing and receiving yards 1 point per full 10 yards, each category truncated toward zero separately. Pass TD 4, interception -2, rush/receiving TD 6, fumble lost -2 (fumbles recovered by the own team are free), two-point conversion 2, each first down 0.25. Receptions are worth 0/0.5/1 for std/half/ppr, and a TE earns an extra 0.5 per reception on top. 300+ passing, 100+ rushing and 100+ receiving yards each add a 3 point bonus. The display string rounds to tenths half away from zero and never shows -0.0.

Why this case matters

Fantasy football points drive weekly matchups and payouts; small unit or boundary mistakes flip results that users dispute.
