Interpolation Process
The system first determines the closest range (from/to) for both Density and Width. The nearest values are determined by searching in the rule table. For sample values, the ranges are as follows:
 
 
Density
Width

If the given Density equals the From value of Density and the given Width equals the From value of Width (case f), the result can be taken from the rule table without any calculation. The same is true if the given values equal the To values.
If only the given Density equals the From value or to value of Density (cases a and e), the system uses interpolation rules to calculate the Width.
If only the given Width equals the From value or to value of Width (cases b and c), the system uses interpolation rules to calculate the Density.
If the given Density is unequal to the From or To value of Density and the given Width is unequal to the From or To value of Width (case d), it is necessary for the system to calculate two extra points based on either the given Density or the given Width, representing the closest range for either Density or Width. Interpolation rules then provide the calculated result.
If the given value for Density or Width is outside the scope of the rule table, it is not possible to calculate a result because the system only handles interpolation, and not extrapolation.
