NCalc 科學計算器 +

Nice app but has some minor issues

As a Wolfram Language user, I was very pleased to find a convenient calculator with a familiar set of functions. A couple of things I wish could be improved though. • Writing scripts in Symja is a wonderful bonus. Do I understand correctly that the calculator uses Symja to do calculations in the backend? Then the two worlds separated (calculator and programming) seem rather sad (given to the coolness of the app as a whole). Why can't I write custom functions using this language? Or can I? Writing functions to be used in calculator expressions is great but is seems to be impossible to implement complex logic in them. Or am I doing something wrong? • Also, it would be great to be able to customize keyboard layout. • The set of possible variable names is unnecessarily small. Latin alphabet is not covered, uppercase and greek letters are not used. • It is inconvenient that it's not possible to copy/cut/move parts of expressions, only the whole thing.

when typed in for example -2^2 it gives -4 when in reality you cannot get a negative when something is squared

Приятный и привычный дизайн. Множество настроек. Встроенные примеры и инструкция по работе. Оформил подписку. Большое спасибо разработчикам!

Ответы показывает в дробях, нет возможности вывести в научном формате или десятичных дробях

App rất tốt. Mình đã mua ủng hộ đội ngũ phát triển.

очень отличный калькулятор есть много рабочих функций и правильный подсчет отличие от некоторых, удачи разработчику в развитие

Лучший инженерный калькулятор

Highly recommended to anyone doing math, no matter at which stage of study or career you currently are.

Also, too many things are locked behind the paywall.
