String Math NuGet Downloads .NET

Calculates the value of a math expression from a string returning a double. Supports variables and user-defined operators.

Creating and using a calculator

ICalculator myCalculator = new Calculator();
double result = myCalculator.Evaluate("1 * (2 - 3) ^ 2"); // 1

// Using custom operators
myCalculator.AddOperator("abs", a => a > 0 ? a : -a);
double result = myCalculator.Evaluate("abs -5"); // 5

// Using custom operator precedence (you can specify an int for precedence)
myCalculator.AddOperator("max", (a, b) => a > b ? a : b, Precedence.Power);
double result = myCalculator.Evaluate("2 * 3 max 4"); // 8

Creating and using variables

// Default variables collection is optional
ICalculator myCalculator = new Calculator(new VariablesCollection
{
	["a"] = 5,
	["PI"] = 3.1415926535897931
});

// Setting or creating variables
myCalculator.SetValue("a", 2);
myCalculator["b"] = 1;

double result = myCalculator.Evaluate("{a} + 2 * {b} + {PI}"); // 7.1415926535897931

Creating and reusing operations

myCalculator.SetValue("a", 5);

// Creating operations (expression tree is optimized and cached)
OperationInfo op = myCalculator.CreateOperation("2 * {a}");
double result1 = myCalculator.Evaluate(op); // 10

myCalculator["a"] = 3;
// Reusing the operation (improved performance)
double result2 = myCalculator.Evaluate(op); // 6

Using the static api: SMath

// Same API as a calculator instance except the Evaluate method
double result = SMath.Evaluate("1 + 1"); // 2
SMath.SetValues(new VariablesCollection { ["myVar"] = 1 });
double result = SMath.Evaluate("1 + {myVar}", ); // 2
