Computes the internal rate of return using an estimated irr of 10 percent.
Calculates IRR using the Newton-Raphson Method.
args- the evaluated function arguments. Empty values are represented with
srcRowIndex- row index of the cell containing the formula under evaluation
srcColumnIndex- column index of the cell containing the formula under evaluation
null. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate to
Double.NaNbe sure to translate the result to
public static double irr(double income)
income- the income values.
public static double irr(double values, double guess)
Starting with the guess, the method cycles through the calculation until the result is accurate within 0.00001 percent. If IRR can't find a result that works after 20 tries, the Double.NaN<> is returned.
The implementation is inspired by the NewtonSolver from the Apache Commons-Math library,
values- the income values.
guess- the initial guess of irr.
Double.NaNif the maximum iteration count is exceeded
