About RLM-12PX
DESCRIPTION:
The RLM-12PX is a programmable financial calculator inspired by the real world HP-12C Platinum or Anniversary calculator. It keeps the classic financial keyboard and its keystroke programming, and adds 30 worksheets designed to bring up the most of your iOS devices for financial, business, mathematical and scientific work.
>Keyboard:
•RPN and algebraic entry, with a four-level stack and storage registers.
•Time value of money, amortization, NPV, IRR, bond price and yield, SL, SOYD and DB depreciation, dates, percentages and statistics directly from the keys.
•Keystroke programs with pauses, conditional tests and branches, written in a full-screen editor and saved and loaded by name.
>Finance Worksheets:
•Account Balance: Calculates the balance of cash transactions and interest applied at arbitrary dates.
•Loan Amortization: Amortization schedule for a single payment or several payments at once.
•Bonds Price & Yield: Calculates the price, yield and effective duration of a bond.
•Black-Scholes Options: Calculates the CALL, PUT and “Greeks” values of a Black-Scholes European option.
•Depreciation: Calculates depreciation with SL, SOYD, DB or MACRS methods.
•Interest Conversion: Nominal and effective interest conversion.
•Time Value of Money: Calculates compound interest problems.
>Business Worksheets:
•Bill-Tip-Split: Calculates the sharing of a bill with tip.
•Break Even: Analyzes the relation Profit = (Price - Var.Cost) • Units - Fix.Cost
•Currency Exchange with manual or on-line rates.
•Inventory Turn Over.
•Percents & Margins: Calculates %Change, %Total and business margins.
•Return on Investment.
>Cash Flows Worksheets:
•Equal Periods: NPV, IRR, MIRR, NFV, payback and discounted payback of cash flows occurring at regular time intervals.
•Unequal Periods: Cash flows occurring at arbitrary dates.
>Statistics Worksheets:
•Probability: 16 probability distributions.
•(X,N)-List Statistics: One-variable statistics.
•(X,Y)-List Statistics: Two-variable statistics and curve fitting.
>Scientific Worksheets:
•Angles & Polar-Rectangular conversions.
•Combinations & Permutations.
•Logarithms, Trigonometric, Hyperbolic and Number Alteration functions.
•Quadratic Equation solver.
•Triangle Solution: Solves plane and spherical triangles.
•Universal Constants: The CODATA physical constants values and descriptions.
•Units Conversion: Physical units conversion, completely customizable.
>General Worksheets:
•Date / Time: Calculates days between dates with Actual, 360 or 365 day calendars, and time intervals between different times.
•Solver: Solves arbitrary equations entered as text for any of the variables, knowing the others.
•Storage Registers: Store and perform operations directly on the calculator's storage registers.
•Memory Content: Clear, back up or restore part or all of the calculator's memory.
•General Settings: Customize display format, decimals, date format, angle unit, sounds, haptics and more.
•Help Documents: Description and ex
