About MathU RPN Calc
MathU RPN is an advanced scientific and financial calculator designed in the spirit of classic HP calculators. MathU RPN is based on the Reverse Polish Notation (RPN) entry system and combines more than 96 functions to create a calculator that meets the needs of professionals who use a calculator every day. First released in 2008, the calculator continues to be updated with new features as iOS improves.
MathU RPN works on the iPhone and iPad. On the iPad, MathU RPN maintains its orientation as the iPad is turned and you can rotate it from portrait to landscape keypad layout via the Rotate button. When the iPad has a hardware keyboard attached, you can type of the names of the buttons the keyboard to execute them -- thus avoiding having to press the calculator keys with your finger. On the iPhone, you can lock it to use the portrait or landscape keypad or let it switch orientations automatically when you rotate your phone.
MathU RPN is an excellent financial calculator. There are functions for computing mortgage amortization and cash flow computations like IRR and NPV, as well as functions for working with dates. Many of the existing financial functions have been extended to handle odd periods (conforming to the same conventions as the HP-12C). In addition, on tall devices (like most iPhones), the financial registers are displayed on the keypad.
MathU RPN is also a programmer's calculator. The A-F keys are available right up front for easy entry in HEX mode and there are many functions for working with integers.
Dr. Clay M. Thompson of Creative Creek has harnessed the computational power of the iPhone to produce an accurate and high performance calculator.

2.0
Jan 14, 2010
MathU RPN 2.0 contains many major improvements to the calculator. Eighteen new functions have been added, some of the existing functions have been made more accessible and the display has been improved.
The update makes MathU RPN 2.0 a better programmer's calculator. The A-F keys are available right up front for easy entry in HEX mode and seven new functions for working with integers have been added.
MathU RPN 2.0 is also a better financial calculator. There are new functions for computing mortgage amortization and cash flow computations like IRR and NPV, as well as functions for working with dates. Many of the existing financial functions have been extended to handle odd periods (conforming to the same conventions as the HP-12C).
The scientific side of MathU RPN has also been improved by adding functions for linear regression as well as computing the percent of total.
In particular, improvements in this update include:
o A two line display option so you can see more of the stack.
o Date functions to compute the day of the week, days between dates, and a date in the future.
o Linear regression functions to compute an estimated y or x value along a fitted line.
o Bit manipulation functions to shift, mask and compute the number of bits in the integer representation of a number.
o Direct access to A-F in HEX mode for easy number entry. The A-F keys replace the financial functions on the keypad when a non-decimal number base is being used.
o Improved display of HEX, OCT, BIN numbers with bit position subscripts for easy interpretation. Very long binary numbers wrap over two lines when they get too big.
o Direct access to storage registers 10-19 via the STO .0 through STO .9.
o Extensions to the financial functions to handle odd period calculations. MathU RPN now conforms to the same conventions as those used on the HP-12C.
o An extension to the random number function RAND to compute random integers when the calculator is in HEX, OCT or BIN mode. In decimal DEC mode, RAND generates a random real value between 0.0 and 1.0.
o A new preference to choose between a single line display or the two line display (Show More Stack) and a preference to choose the date format (M.DY vs D.MY).
o [Bug fix] Word size setting in the preferences now supports the full 48 bits.
