Missing functions on the HP Prime!!!??? :(  Namir  08212013 After exploring the wealth of math functions and polynomials on the HP Prime emulator, I noticed that the following functions were missing: 1) Bessel functions 2) Bernoulli numbers 3) Bernoulli polynomials The history of HP calculator has supported calculating some of the Bessel functions, of integer orders, in the Math Pacs of various vintage calculators (in fact I was playing with the HP67 Math Pac today and calculating Bessel function values). The Bernoulli numbers and polynomials have never been implemented in any HP calculator math pac. I am asking about these functions since the Prime now supports, for the first time, various orthogonal polynomials (Laguerre, Legendre, Hermite, and Chebyshev). So why not add Bessel and Bernoulli functions as new functions??? Namir

Re: Missing functions on the HP Prime!!!??? :(  Tim Wessman  08212013 More important to get things right, with a smaller subset of functions that are fully tested and well documented, before starting the "lets lump in everyone's favorite function" game... IMHO

Re: Missing functions on the HP Prime!!!??? :(  Eddie W. Shore  08212013 That is the awesome part of calcualtors being programmable; it can be used to fill any missing holes and customize the calcualtor.
Re: Missing functions on the HP Prime!!!??? :(  Mic  08222013 exactly, just program it ! Edited: 22 Aug 2013, 2:32 a.m.
Re: Missing functions on the HP Prime!!!??? :(  Eddie W. Shore  08222013 I agree, the INPUT command is very limited. I usually use passthrough arguments, (myfunc(a,b,c)) instead of INPUT. At least passthrough arguments allow various types of input.
Re: Missing functions on the HP Prime!!!??? :(  Gilles Carpentier  08222013 INPUT allows not only numbers but also also strings (between ""), matrices ( [[]]) , vectors, list etc ...
