A landing with 6 pounds of Silvergray Rockfish.

The landed weight is stored in eLandings as 6.0000 pounds with condition_code 3.

On import into the Alaska Region database the landed weight in metric tons is calculated:

6.0000 / 2204.6226 = .00272155424697179462825065841201119865

(PL/SQL does this calculation with 38 decimal digits of precision)

The result is then stored in a database column with three decimal digits of precision, i.e., 0.003 metric tons.

The product recovery rate of 0.98 is applied to the landed weight:

0.003 / 0.98 = 0.00306122448979591836734693877551020408

which is stored with 3 decimal digits of precision as 0.003 metric tons.

Metric tons are converted into pounds:

0.003 * 2204.6226 = 6.6138678

which is reported in eLandings with four decimal digits of precision as 6.6139. Standard price for this species/gear/port is $0.31, and the estimated observer fee is calculated as:

6.6138678 * 0.31 * 0.0125 = 0.0256287377250 which is reported in eLandings with two decimal digits of precision as $0.03.
