package `financial` features common financial functions, and is intended to be a golang version of [numpy's financial functions](https://docs.scipy.org/doc/numpy/reference/routines.financial.html).

## Supported Functions:

- NPV(r, values): returns the NPV (Net Present Value) of a cash flow series given an interest rate r, or an error. See [usage example](https://godoc.org/github.com/orcaman/financial#example-NPV).

- IRR(values): returns the Internal Rate of Return (using newton raphson approximation). See [usage example](https://godoc.org/github.com/orcaman/financial#example-IRR).

- FV(pv, r, compoundedAnnually, n): gets the present value, the interest rate (compounded annually if needed) and the number of periods and returns the future value. See [usage example](https://godoc.org/github.com/orcaman/financial#example-fv).

## TODO:

- pv(rate, nper, pmt[, fv, when])	Compute the present value.

- pmt(rate, nper, pv[, fv, when])	Compute the payment against loan principal plus interest.

- ppmt(rate, per, nper, pv[, fv, when])	Compute the payment against loan principal.

- ipmt(rate, per, nper, pv[, fv, when])	Compute the interest portion of a payment.

- mirr(values, finance_rate, reinvest_rate)	Modified internal rate of return.

- nper(rate, pmt, pv[, fv, when])	Compute the number of periodic payments.

- rate(nper, pmt, pv, fv[, when, guess, tol, ...])	Compute the rate of interest per period.
