![]() ![]() TAYLR: Compute the taylor expansion of a selected order and accuracy of a MVAR function (Interactive app) Note: The convention of days of the week is 1-Monday, 2-Tuesday, 3-Wednesday, 4-Thursday, 5-Friday, 6-Saturday, 0-SundayĬollection of calculus related functions accessible through a CUSTOM menu.ĭERIV: Compute the derivative of a selected order and accuracy of a MVAR function (Interactive app) STP→D: Convert a ESA Solar Orbiter mission planning cycle into a date SDATE: Compute current ESA Solar Orbiter mission planning cycleĭ→STP: Convert a date into a ESA Solar Orbiter mission planning cycle G→T: Conver GPS time (GPS week and seconds of the week) into a date T→G: Convert a date into GPS time (GPS week and seconds of the week) U→T: Convert a UNIX time into a date (based on Thomas Okken's program: ) T→U: Convert a date into UNIX time (based on Thomas Okken's program: ) UTIME: Compute current UNIX time (based on Thomas Okken's program: ) YWD→D: Convert a year, ISO week and day of the week in a date Menu to hyperbolic trigonometric functions.Ĭollection of date related functions accessible through a CUSTOM menu.ĭDAYS (Free42 builtin function): Compute number of days between 2 datesĭATE+ Free42 builtin function): Compute the addition of a date and number of daysĭ→DOY: Convert a date into the day of the yearĭOY→D: Convert a day of the year into a dateĭ→YWD: Convert a date into a year, ISO week and day of the week The menu adds a the LGyX function to compute base-y logarithm. So far, the purpose of this function is toĬreate a CUSTOM menu with the top row shifted funcions. MAIN, MATH, HYP, DATES, UNIT, CPX, CONSTANT, CALC, DEBUG The summary of the functions are (the details of input/output of each function is embedded in the source code): The main idea of this collection is to make use of the CUSTOM menu as much as possible in the same way that it can be done in HP48G. So, in order to use the code in DM42, you would need to add the changes of Free42 in the DM42 code. On the other hand, notice that the code uses functionalities available in Free42 v3.0.0. So, I decided to share it here in case they are helpful to someone else. ![]() I have been exploring the programming capabilities of DM42/Free42 and I wrote some functions that I think that they will give some extra functionality to my calculator. ![]()
