rpn-programming

This program runs the Collatz (3n + 1) sequence on the SwissMicros DM32. From any positive whole number, the calculator counts the steps to reach 1 and finds the highest term along the way, and can show or stop on every term as it is calculated.

This program suite provides time value of money calculations on the SwissMicros DM32. The calculator solves for any one of the number of payments, interest rate, present value, payment, or future value, using an annual or periodic rate, and calculates annuity future values and percent of total.

This program suite explores the logistic map on the SwissMicros DM32. The calculator iterates the map for any growth rate and starting value, shows each iterate as it runs, and calculates the Lyapunov exponent that separates stable cycles from chaos.

This program suite provides celestial and marine navigation on the SwissMicros DM32. The calculator finds sunrise, sunset, and the sun’s position for any date and place, solves closest point of approach from a radar observation, and calculates great-circle routes, using the datetime32 and conversion32 Statefiles.

This program suite provides bus safety and route planning on the SwissMicros DM32. The calculator solves braking from speed and any one known value, safe stopping distance for reaction time, road conditions, and slope, and kickout over the curb on departure, and plans the buses a route needs and the weight of its passenger loads.

This program suite provides transit layover assessment on the SwissMicros DM32. The calculator scores a scheduled layover by its length and position in the shift, then runs a Monte Carlo simulation using recorded lateness data to estimate the break an operator actually receives.

This program suite provides circular-orbit calculations on the SwissMicros DM32. From any one known value (height, velocity, circumference, period, or revolutions per sidereal day), the calculator solves the rest, with stored constants for the SUN, the planets, and the MOON.

Comprehensive date calculation capabilities for the SwissMicros DM32 calculator, replicating and extending the date functions found on the classic HP-12C financial calculator. The programs enable date arithmetic, and day-of-week determination.

Joy of Postfix Calculator App

This program suite provides one-key unit conversions on the SwissMicros DM32. The calculator converts astronomical units, miles, nautical miles, yards, and feet to and from metric, and converts between currencies at an exchange rate stored in a Global register.

This program suite provides geodetic calculations on the SwissMicros DM32 using the WGS 84 ellipsoid. The calculator finds the Earth’s radius, the circumference of the parallel, and the speed of the Earth’s rotation at any latitude, and the distance to the horizon from any height.

This program suite provides comprehensive mine clearance operations planning for Mine Countermeasures (MCM) assets. The calculator determines the number of passes required to achieve a specified confidence level that mine density has been reduced to an acceptable threshold.

This program suite produces Chess960 (Freestyle Chess) starting positions on the SwissMicros DM32. The calculator decodes Scharnagl numbers 0 to 959 into an 8-digit layout code, giving a random position, the layout for a known number, or a random sequence seeded by both players.

This program suite provides sportsbook odds calculations for two-way markets on the SwissMicros DM32. The calculator removes the bookmaker’s margin to find each side’s fair probability, calculates the profit on a wager, and converts between American and decimal odds.
