CasioSCHULRECHNER Modell FX 5800 P, BATTERIEBETRIEB, Black

I picked this up to be my daily driver calculator. I don't like to use software calculators since they, and the platform they run on, are routinely updated and I can't expect them to behave the same from one update to the next.This calc is easy to program and keeps its memory when you change batteries (you have to follow the instructions!). The programming language is very simple and that makes it easy to create programs without having to learn an overly complex language for one device.Mine came with an English insert in the fold over cover. I've noticed that some are in another language in various pictures.There are enough direct access functions on the buttons to make me happy. Any calculations that are annoying (too many menus, etc) should simply be programmed into it to remove the annoyance.I love that it takes a regular AAA (LR03, NOT LR44 as the description states) battery, that was a main drawing point. I hate coin cell batteries (even though I own a few HP calculators that run on them and I love those calcs -- RPN!).I haven't really found any negatives to the calculator yet. I also suggest spending the ten bills on the HP Prime app if you have an Android device. It is an amazing platform and very fast. One huge benefit of a software calculator is that it is presented on a lit screen so you can use it in the dark or dimly lit places. I still prefer a non-software calculator most of the time but having the Prime on hand wherever your phone is can be quite handy and it can present visuals for others.

This calculator fills an uncommon niche in the calculator world nowadays. It's programmable, but can't graph. Typically you can get a cheap scientific calculator for $20 that isn't programmable and can't graph or you can spend $100+ and get a calculator that is programmable and can graph. This calculator falls in between those two main categories. I like it because it has a multi-line display and big function library. You can program it in Casio's version of BASIC that you'll be familiar with if you've ever used one of their graphing calculators. It also has a TON of memory for storing programs.Other good things about this calculator are the familiar Casio interface (well, familiar if you've used a Casio before, TI users probably won't like it), generous sized and easily viewable screen, and good build quality.The only downside I can see for this calculator is that it can't connect to another calculator or computer so you can't transfer programs and files, any programs you want to use have to be keyed in by hand.

It came with instruction manual in Japanese !

Fits in a large shirt pocket, and seems durable. Good, well designed, user interface. Excellent functionality. No unit conversions. Not RPN, but better in every other way than the HP35s. Fantastic.

Muy buena pero no como las Casio antiguas. Lo malo es que el manual venía sólo en japonés.

Nice unit. I wish it was backlit but I can't dock it any stars for that.

It is casio; the best. Please go back to the plastic cover. It is simply safer, manegeable, and better. The cover that comes now force you to spend more time taking care of protecting it than working on it. Thank you

This is a remarkably powerful calculator with a full Basic-like programming capability.

que esta nuevo pela descargada pero la remplace por una nueva y todo muy bien gracias

Good calculator but it is not made in Thailand. Chinese product.

tengo calculadoras científicas de varias marcas,---> hp, texas instrumens, sharp .... CASIO.. me gustan las calculadoras, . Prácticamente todas las calculadoras científicas tienen las mismas funciones, trigonometría, logaritmos, potencias, raices . . . .hay una marca que se diferencia de las otras, las HP, casi todos sus modelos usan una forma inusual de introducir los datos, RPN, notación polaca inversa, hay grandes defensores de este sistema, y hay a quien no le gusta. Este modelo de CASIO, aparte de ser muy sencilla de usar, estas viendo en la pantalla las operaciones como si las escribieses en una libreta, tiene algo muy bueno . . . . puedes escribir una formula, todo lo compleja que se quiera, asignas variables, letras que después la calculadora memoriza y que te ira pidiendo, y con solo ir introduciendo esas variables, la calculadora resolverá ese calculo, sin que tu tengas que repetir y volver a reescribir la formula. Eso es comodísimo y ahorra un montón de tiempo. De todas las calculadoras que tengo, la CASIO fx 5800p es la que mas me gusta y la que mas uso, para mi es la mejor, y no es excesivamente cara, 63 € para todo lo que puede hacer no es mucho dinero

This is Asia model Casio calculator.

In ricordo della mia ottima Sharp EL-5120, che dopo decenni di avventure mi ha lasciato, ho scelto questa; l'unica sul mercato che ha le funzioni di programmazione in Basic, senza cas ne grafici. Per i grafici ed il cas uso hp prime e ti-nspire. Quando si vuole una scientifica con la tastiera classica, senza fronzoli e con sistema di programmazione in Basic, questa è una scelta obbligata. Non ce ne sono molte in giro (forse nessuna). Non mi piaceva l'idea della custodia a libro, però devo dire che non è male. Molto leggera ed il display a matrice ha una ottima leggibilità in ogni situazione. Ha tutte le funzioni che si possono cercare in una scientifica, incluse costanti per un rapido inserimento, matrici, numeri complessi,...
