-    The NPV calculation may be applied to several ``rates`` and ``cashflows``
-    simulatneously. This produces an array of shape
-    ``(len(rates), len(cashflows))``.
-
-    >>> rates = [0.00, 0.05, 0.10]
-    >>> cashflows = [[-4_000, 500, 800], [-5_000, 600, 900]]
-    >>> npf.npv(rates, cashflows).round(2)
-    array([[-2700.  , -3500.  ],
-           [-2798.19, -3612.24],
-           [-2884.3 , -3710.74]])
-
-    The NPV calculation also supports `decimal.Decimal` types, for example
-    if using Decimal ``rates``:
-
-    >>> rates = [Decimal("0.00"), Decimal("0.05"), Decimal("0.10")]
-    >>> cashflows = [[-4_000, 500, 800], [-5_000, 600, 900]]
-    >>> npf.npv(rates, cashflows)
-    array([[Decimal('-2700.0'), Decimal('-3500.0')],
-           [Decimal('-2798.185941043083900226757370'),
-            Decimal('-3612.244897959183673469387756')],
-           [Decimal('-2884.297520661157024793388430'),
-            Decimal('-3710.743801652892561983471074')]], dtype=object)
-
-    This also works for Decimal cashflows.
