Calculates the NFL quarterback rating.
Formula: ((at=((100 * comp / att)-30)*.05)+(bt=(yards/att-3)*.25)+(ct=(td/att)*20)+(dt=2.375-(25*intr/att)))*0 + (max(min(at, 2.375), 0) + max(min(bt, 2.375), 0) + max(min(ct, 2.375), 0) + max(min(dt, 2.375), 0))*100/6
Comp: The number of completed passes.
Att: The number of attempted passes.
Yards: The total passing yards.
TD: The number of touch downs.
Intr: The number of interceptions.

Yards | 4,213.1 | Calculates the Yards value. |
Note the technique used for this complex formula. The four temporary values, at, bt, ct and dt are calculated first and then used in the max/min formula as given in the reference. To see the value of a variable just enter the name of the variable in formula mode. For example, "=f at =" will display the at value of 2.0141.
