I'm doing a scientific calculator app but I don't know which library I should use. I need a library that can solve scientific math expressions and if it can solve functions even better. I'm looking for one that works with a given string and solves it without having to parse any operator, like exponents or roots.
What library do you recommend me? Thanks.
You can use JavaScript as a representation of your mathematical expressions. It's a full-flege language, and all mathematical expressions should be possible (although I am not a JavaScript programmer, so I can't say that with 100% certainty). Additionally, Nashhorn, a Javascript engine, is built into the JVM so there is no need for additional dependencies. If you need something in a slightly different format than Javascript requires, you could easily make simple modifications to the user's input and/or add JavaScript boilerplate before and/or after it.
