RPNCalcSeries-12C+ emulates the functionalities of HP-12C Programmable Financial Calculator (HP-12C is a trademark of Hewlett Packard Co.),with some extra features:

1) Graphs and Lists for:

- NPV=f(i), an enormous facility to help finding IRR;
- PV=f(OD);
- PV=f(FV);
- PV=f(PMT);
- PV=f(n);
- PV=f(i);
- PMT=f(OD);
- PMT=f(FV);
- PMT=f(PMT);
- PMT=f(n);
- PMT=f(i);
- FV=f(OD);
- FV=f(FV);
- FV=f(PMT);
- FV=f(n);
- FV=f(i);
- SumPMT=f(n);
- SumInterest=f(n);
- Amortization=f(n); and
- Balance=f(n)

2) Smart Help - an error sensitive context help, that brings for each key, the meaning of a certain error condition and what to do to correct the situation. Besides that, it is also an User Guide reference

3) Calculation of Balance, Sum of Amortization, Sum of Interest and Sum of PMT

4) Odd Days are not limited to a decimal fraction. They could be positive or negative, integer or not integer values

5) 27 Cash Flow registers, instead of 20

6) A much easier way to perform IRR calculation, through graphs and lists

7) Time Now key

8) Time conversion: hms-hr and hr-hms

9) Calendar key

10) Day of week calculation

11) a much more powerful programming language, with a complete on-line guide

12) Bond Price and Yield are calculated taking into consideration either "30/60" day basis or "actual" day basis

13) All is visual - you don't have to memorize any key combination to access calculator functionalities

14) Updates / upgrades are life-time free of charge
