Calculator

A calculator written in C#, supporting expression calculation and simple function.

How to use

I have made a calculator-like UI. However, the class is written to support Assembly reference.

Use using Net.AlexKing.Calculator.Core to import the core classes. For normal expression calculation, use

Calculate cal = new Calculate("1+2");
Operand operand = cal.DoCalculation();
double result = (double)operand.GetValue();

The static method AddFunction in class Function support simple user-defined functions, the function must follow the BNF:

function::=<FunctionName> "(" <Parameter>{,<Parameter>} ")=" <Function Expression>

For example

Function newFunc = new Function("test(x,y)=x*5+y");
newFunc.Add();
Calculate cal = new Calculate("test(1,2)");
Console.WriteLn(cal.DoCalculation().GetValue());

The result will be 7.
