description: "Net present value of a cash flow series, discounted at a declared periodic rate. Accepts either caller-supplied period offsets or dated cash flows converted to years under a declared day-count convention (30/360, ACT/360, ACT/365, or a simplified ACT/ACT). Deterministic pow via Taylor-series exp/ln, no engine transcendentals. Foundation primitive for downstream valuation and lease/loan analytics."
