Performs the individual discounting operations required in life-cycle cost analysis. Discount computes present values of future
and periodic amounts, future values of present and periodic amounts, and annual-value equivalents of present and future
amounts. Discount also computes the discount factors corresponding to each of these operations, enabling it to substitute for
extensive tables of discount factors. It accepts non-integer discount rates, study periods, and price escalation rates and can
access the DOE projections of energy price increases used in the BLCC program.
