RLM-10CX

The RLM-10CX is a programmable RPN calculator with a special focus on science and engineering. It is based in the Hewlett-Packard HP-10C calculator. It keeps the classic scientific keyboard you already know and its keystroke programming, and adds a complete set of menus and worksheets designed to bring up the most of your iOS devices and , at the same time, conserving the easy of use and all functions originally provided by the real calculator. >Keyboard: •RPN entry with a four-level stack, LAST X and 20 storage registers with register arithmetic. •Trigonometric, logarithmic and power functions, polar-rectangular and hours conversions, statistics with linear regression and estimates directly from the keys. •Keystroke programs of up to 1000 lines with 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. •Cash Flows: NPV, IRR and related answers for equal periods or for cash flows occurring at arbitrary dates. •Depreciation: Calculates depreciation with SL, SOYD, DB, DBX 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. >Date / Time: •Calculates days between dates with Actual, 360 or 365 day calendars, and time intervals between different times. >Statistics Worksheets: •Probability: 16 probability distributions. •(X,N)-List Statistics: One and two variable statistics and curve fitting. •(X,Y)-List Statistics: Two-variable statistics and curve fitting with six regression models. >Scientific Worksheets: •Angles & Polar-Rectangular conversions. •Complex Numbers: Arithmetic and functions of complex numbers in cartesian or polar form. •Combination & Permutation. •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. •3D Vectors: Operations with vectors in cartesian, spherical or cylindrical coordinates. >Convert Worksheets: •Angles & Polar, Currency Exchange, Interest Conversion and Units Conversion: physical units conversion, completely customizable. >General Worksheets: •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, left-handed layout, sounds, haptics and more. •Help Documents: Description and examples of all the calculator worksheets and features. >Editors: To create or edit data •(Date,Trx) and (Date,CF) Lists: Dated transactions and cash flows. •(X,N) and (X,Y) Lists: Data for cash flows and statistics. •Program, Solver Equation and Units Database.
