## What is eXpimal?

The most functional math logic calculator.
This application has the functions as follows:
- creating truth tables;
- finding DNF, CNF, PDNF and PCNF;
- finding Zhegalkin polynomial (Undetermined coefficients method and Pascal's triangle method);
- making a Karnaugh map;
- minimizing Boolean function with equivalence conversion (both briefly and in details);
- minimize partially defined functions;
- belonging to the Post classes;
- plotting logical schemes (both IEC and ANSI schemes);
- plotting ladder diagram;
- minimizing functions using McCluskey method.
Boolean functions may be displayed as multiple characters.
Unary operation "negation" may be displayed either as a single character or in the form of an overline.

Maximum number of variables in the function is limited by 6.
Maximum number of function-embedded negations is limited by 5.
Maximum number of characters in the function is limited by 64.
Karnaugh maps, PCNF and PDNF functions, Zhegalkin polynomial and the McCluskey method only may be used for operating a value vector.
The modulus of vector shall contain 4, 8, 16, 32, or 64 characters.
The values of 0 and 1 may be used in this function but it will be subject to simplification only.
The implication is inadmissible for plotting a logical scheme.

This application demonstrates intuitively understandable and trouble-free operations. All results are shown in details along with comments.

### 4/5 — Топ

*2024-04-04*

Приложение хорошее, но где знак равно? (=)

**Developer response:** Здравствуйте.
В алгебре логики нет такой операции.

### 5/5 — ¡Genial!

*2024-02-25*

Me ha ayudado mucho para comprender y aplicar la lógica, tanto en circuitos de compuertas, como en controles eléctricos conmutados,me gustaría que al generar el diagrama con compuertas se presionaran las entradas y se  encendieran las salidas correspondientes.
Gracias.

### 3/5 — Как стереть

*2022-05-17*

Все ок , пример решён. Но не работает кнопка DEL и не могу стереть этот пример и записать новый

**Developer response:** Здравствуйте. Удаление работает. У Вас скорее всего курсор необходимо сначала вывести из под отрицания.

### 5/5 — Спасибо!

*2021-10-11*

Очень хорошее приложение. Спасло меня на информатике. Стоит своих денег. Если вы гуманитарий как и я и информатика для вас - омут, то смело качайте. Спасибо разработчикам!!!

### 1/5 — игнор

*2021-06-24*

купил приложение и тут такая проблема, есть ограничение на ввод значений, то есть я не могу ввести полное количество дизъюнкций + не могу ввести ЦИФРЫ, что самое обидное, чтобы построить ту же таблицу Мак-Класки, я подумал что есть 0 и 1 напишу в двоичном коде, но и тут места нет + нет пробела, а в скобках считает не правильно.

### 5/5 — Достойное приложение

*2021-06-17*

Хороший и расширенный функционал. Понятный интерфейс. Благодаря ему сдал экзамен на отлично и закрыл сессию. Стоимость оправданная.

### 3/5 — .

*2020-12-20*

В приложении отсутствует возможность находить разность множеств?

### 5/5 — Анонимно

*2020-12-16*

Скачал по совету друга. Ценника не было. Списали 179 рублей. Деньги от слова не жалко. Кидок это очень плохо. Работает все хорошо.

**Developer response:** Здравствуйте.
Цена приложения на данный момент 179 руб. Оне не бесплатное. Бесплатно скачать его невозможно. Ценник всегда указан на странице приложения. Никакого "кидка" нет.

### 1/5 — Crashing

*2020-09-28*

The app is crashing once it loads, please fix the issue

**Developer response:** Sorry, there was a small problem that has been fixed for a long time.

### 1/5 — Обман

*2020-03-12*

Приложение не работает, обман, не тратьте деньги

**Developer response:** Здравствуйте. 
Напишите, пожалуйста на почту maxdm@bk.ru в чем проблема.
