Using built-in functions

TO SUPPORT MY WORK, ORDER A COMMERCIAL LICENSE
THANK YOU!

The tutorial consists of more than 180 live examples from 40 sections. Each of the examples can be copied and run on your own environment. In addition, mXparser provides an extensive collection of over 500 built-in math functions, expressions and symbols. Familiarize yourself with the scope and the syntax. Live testing is the best way to learn. Good luck! 🙂

Below is the code for JAVA, the code for C# is almost identical.

Case 1: Unary function

$$\sin(2)-\cos(3)$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("sin(2)-cos(3)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: sin(2)-cos(3) = 1.8992899234261271

Case 2: Binary function #1

$$\min(3,4) + \max(-2,-1)$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("min(3,4) + max(-2,-1)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: min(3,4) + max(-2,-1) = 2.0

Case 3: Binary function #2

$$10\choose 5$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("C(10,5)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: C(10,5) = 252.0

Case 4: Function with 3 arguments #1 – condition checking

$$\text{if}(a, b, c)=\begin{cases}\quad b&\text{if}\quad a\text{is true}\\\quad c&\text{otherwise}\end{cases}$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("if(2<3, 1, 0)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: if(2<3, 1, 0) = 1.0

Case 5: Function with 3 arguments #2

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("if(3<2, 1, if(1=1, 5, 0) )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: if(3<2, 1, if(1=1, 5, 0) ) = 5.0

Case 6: Function with n-arguments

$$f(x_1,x_2.\ldots,x_n)$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("gcd(4,2,8,20)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: gcd(4,2,8,20) = 2.0

Case 7: Function with even number of arguments

$$\text{iff}(a_1, b_1;a_2, b_2;\ldots,a_n, b_n)=\begin{cases}b_1&\text{if}\quad a_1\text{is true}\\b_2&\text{if}\quad a_2\text{is true}\\\ldots&\ldots\\b_n&\text{if}\quad a_n\text{is true}\end{cases}$$

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("iff( 1>2, 1, 3<2, 2, 5>3, 3, 7 < 3, 4 )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: iff( 1>2, 1, 3<2, 2, 5>3, 3, 7 < 3, 4 ) = 3.0

Case 8: Equivalent to case 7 – more convenient form of marking parameters

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("iff( 1>2, 1; 3<2, 2; 5>3, 3; 7 < 3, 4 )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: iff( 1>2, 1; 3<2, 2; 5>3, 3; 7 < 3, 4 ) = 3.0
