Recomputes a fund's net-asset-value-per-share from supplied holdings (quantity × supplied price, multi-currency with supplied FX), accruals (income and expense, with a declared day-count convention), liabilities, and shares outstanding, using fixed-point money math throughout (no float accumulation). Applies a declared rounding mode (e.g. $0.0001 for a money-market fund vs $0.01 for a standard fund) and returns a full component breakdown. First entry of the Funds/NAV family, alongside the forthcoming NAV-error materiality tester and expense-ratio calculator.

What this does NOT prove
Every price and FX rate here is supplied by you and merely asserted: this tool performs zero market-data lookups (zero-egress, no network calls of any kind). It recomputes the arithmetic over your declared inputs and attests that computation ran correctly. This is never a fair-value opinion, never an independent valuation, and never live or real-time market data. A NAV receipt from this tool proves "this arithmetic, over these declared inputs": nothing about whether the declared prices are accurate. 40-Act/UCITS citations below are informative context only.
Fixed-point (BigInt) money math throughout: every value is parsed from its decimal string representation, never via floating multiplication, so there is no float-accumulation error anywhere in the arithmetic path. Only the final NAV-per-share is rendered to the declared decimal places using the declared rounding mode.
⚠ DECISION-SUPPORT DRAFT. Not a fair-value opinion, not an independent valuation, not live market data. Pricing/FX inputs are supplied and asserted only.
