Byces.Calculator 1.1.0

Byces.Calculator

A simple .NET calculator that solves string math expressions

Usage example

string expression = "2 + 5 * 3";

MathResult mathResult = MathResultBuilder.GetMathResult(expression);
// or
MathResult mathResult = new MathResultBuilder().WithExpression(expression).Build();

if (mathResult.IsValid) // true
{
    Console.WriteLine(mathResult.Result); // 17
}
else
{
    Console.WriteLine(mathResult.ErrorMessage);
}

Public Models

MathResult (readonly struct)

MathResultBuilder (class)

Building expressions

Before showing some syntax examples, here are some observations:

• Numbers, operations and self operations are not case sensitive
• The builder is not sensitive to whitespace and using it has a low impact on performance

// You can use signs to represent negative and positive numbers
string expressionExample1 = "-5 + +5";

// You can use parentheses to set priorities in the expression
string expressionExample2 = "((2 + 5) * 2) * 3";

// You can also represent numbers like this
string expressionExample3 = "1E+3";

// This is an expression with two operations and two self operations
string expressionExample4 = "fact(2 + 3) * fact3";

Available operations

string expression1 = "2+4+6";
string expression2 = "2 add 4 add 6";
