FormulaEngine.Net

FormulaEngine.Net Is a Simple FormulaEngine For .net Application (C#,VB,...) Today This Engine Support This Operations (+,-,/,*,Pow,Log,Log10,Sin,Cos,Sqrt,Tan)

Operation Syntax:
sin(variable)
cos(variable)
tan(variable)
pow(variable1,variable2)
sqrt(variable)
log(variable)

Sample:
var formula = "(log(pow(a,b)))+(cos(n)*(tan(m)))";

Exmaple:

Input:

1. A+B

2. A=1

3. B=1

OutPut:

2

variables must be in the dictionary object:
Dictionary(variableName, variableValue)

please be carefull in formula text. count of '(' must be equal with count of ')' for example: ((sin(a))) .

Sample Code:

        Dictionary<string, double> variables = new Dictionary<string, double>();

        variables.Add("a", 2);
        variables.Add("b", 3);
        variables.Add("c", 5);
        variables.Add("k", 4);
        variables.Add("f", 4);
        variables.Add("d", 8);
        variables.Add("var1", 2);
        variables.Add("some", 3);
        variables.Add("n", 30);
        variables.Add("m", 45);
        
        FormulaEngine.Net.Engine ap = new FormulaEngine.Net.Engine(variables);
        double result = 0;

        result = ap.Process("(var1*alakiy5/c)*log(c+k)");

        result = ap.Process("(var1*alakiy5/c)*log10(log10(c+k))");//-0.024409488559873654

        result = ap.Process("((log10(a))*b)+pow(a,b)");//8.9030899869919438

        result = ap.Process("((log10(a))*b)+pow(pow(a,c),b)");//32768.90308998699

        result = ap.Process("log10(pow(a,b))");//0.90308998699194354

        result = ap.Process("var1+c");//7

        result = ap.Process("sqrt(n)"); //..

        result = ap.Process("(log(pow(a,b)))+(cos(n)*(tan(m)))"); //..
