Time Value of Money - a Python package for mathematical interest theory, annuity, and bond calculations.
See ex_8_9_8_test.py in the testing suite. olb_r and olb_p should return the accumulated loan amount when t=1/12. Instead, an amount smaller than the loan amount is returned which is not...
this will make it consistent with the coupons Annuity object
See Vaaler and Daniel, example 5.5.8. I think I would be able to solve this problem more easily if I could solve for an arithmetic progression amount.
This won't pop up with the common growth rates but for complex growth patterns, it's possible to have multiple solutions. See problem Vaaler & Daniel 1.8.5 for a simple case...
it would be nice if we had two amount functions, we can see over what intervals inside an investment window where one function overtakes the other (see Vaaler & Daniel,...
the source book says that we cannot use the balance when j_tilde != j, but the book does just that in example 6.7.9. We need to check whether this is...
The examples in the book have formulas for bonds with level coupons, but we should enable calcs for nonlevel coupons
It may not be a common case for people to intentionally create an annuity with 0 payments, but this happened when trying iterate through annuities of various terms when calculating...
