mXparser is a super easy, rich, fast, and highly flexible math engine library that includes expression parser and expression evaluator (parser and evaluator of mathematical expressions / formulas provided as plain text / string). The software provides easy-to-use APIs for JAVA, Kotlin, Android, C++, C# .NET / .NET Core / MONO (including compatibility with CLS / Common Language Specification: F#, Visual Basic, C++/CLI). The expression parser comes with extensive documentation, an easy-to-follow tutorial, a step-by-step “Hello World” projects and a summary of performance tests. The formula parser / evaluator is distributed under the DUAL LICENSE model, that is designed to meet the needs of both Non-Commercial Use as well as Commercial Use.

mXparser works at runtime, which means it can fully execute end user commands while the entire application is running

Few examples of string equivalent to the math formula notation:

MATH EXPRESSION	MXPARSER EXPRESSION STRING
$1+2$	“1+2”
$1+\frac{2}{3} + (4\cdot 5-10)$	*1+2/3 +(45-10) – classic or 1+2_3+(45-10)* – with fractions or 1+2_3+(4×5-10) – with fractions and Unicode math or 1+2÷3+(4⨉5-10) – with fractions and Unicode math or 1+2÷3+(4∙5-10) – with fractions and Unicode math
$2x+\sin(y)$	*2x+sin(y) – classic or 2x+sin(y)** – with implied multiplication
$\int_{-1}^{1}\sqrt{1-x^2}$	int( sqrt(1-x^2), x, -1, 1) – classic or ∫( sqrt(1-x^2), x, -1, 1) – with Unicode math or ∫( √(1-x^2), x, -1, 1) – with even more Unicode math
$\sum_{n=1}^{100}\frac{1}{n^2}$	sum(n, 1, 100, 1/n^2) – classic or ∑(n, 1, 100, 1/n^2) – with Unicode math Σ(n, 1, 100, 1÷n^2) – with Unicode math (another symbols)
$n\choose k$	C(n,k)
$fib_n=\begin{cases}fib_{n-1}+fib_{n-2}\\fib_1=1\\fib_0=0\end{cases}$	fib(n) = iff( n>1, fib(n-1)+fib(n-2); n=1, 1; n=0, 0)
$2\frac{3}{4} + 3\frac{2}{3}+\frac{1}{2} $	2_3_4+3_2_3+1_2 – with fractions or 2+3/4+3+2/3+1/2 – classic
$f(x,y)=x^2+\sin x+\cos y$	f(x,y) = x^2+sin(x)+cos(y)
$\sqrt{\pi}$	sqrt(pi) – classic or √ℼ – with Unicode math

Just a few examples of math expressions with corresponding mXparser syntax
