Fractions

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

The tutorial consists of more than 200 live examples from 50 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: Fraction (proper) as Number Literal

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("1_2");
mXparser.consolePrintln(e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.3] 1_2 = 0.5

Case 2: Improper Fraction as Number Literal

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("-6_5");
mXparser.consolePrintln(e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.3] -6_5 = -1.2

Case 3: Fraction (Mixed Number) as Number Literal

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2_3_5");
mXparser.consolePrintln(e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.3] 2_3_5 = 2.6

Case 4: Fraction (Mixed Numer) and Improper Fraction in one Number Literal

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2_12_5");
mXparser.consolePrintln(e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.3] 2_12_5 = 4.4

Case 5: Operations on Fractions

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("1_2-6_5*2_3_5/2_12_5");
mXparser.consolePrintln(e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.3] 1_2-6_5*2_3_5/2_12_5 = -0.2090909090909091

Case 6: Represent double as Fraction

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("1_2-6_5*2_3_5/2_12_5");
double resultAsDouble = e.calculate();
String resultAsFraction = mXparser.toFractionString(resultAsDouble);
mXparser.consolePrintln(e.getExpressionString() + " = " + resultAsFraction);
[mXparser-v.5.0.3] 1_2-6_5*2_3_5/2_12_5 = -23/110
