Eval.net

Easily evaluate simple expressions on the go...

This is a port of the BigEval.js library

Features:

  • Evaluate basic math operators (5 * (4 / 3))
  • Use constants (x * 27 / 4)
  • Support for pre-defined function calls (30 * pow(24, 6) / cos(20))
  • Support for custom function calls
  • Support for logic operators (26 * 3 < 100 - returns a bool value)
  • Support for bitwise operators ((1 << 2) == 4)
  • Support for string values ("test" + 5 == "test5")
  • Customize the type that is used for numeric values in the expression.
  • Customize the code behind the execution of any of the operators.
  • Support for compiling an expression and running multiple times while supplying different constants

Nuget

Install-Package Eval.net

Usage

using Eval.net;

var result1 = (double)Evaluator.Execute("12+45*10", EvalConfiguration.DoubleConfiguration);
var result2 = (double)Evaluator.Execute("30 * pow(24, 6) / cos(20)", EvalConfiguration.DoubleConfiguration);

var compiled = Evaluator.Compile("5 * n", EvalConfiguration.DoubleConfiguration.Clone());

compiled.SetConstant("n", 8);
var result3 = (double)compiled.Execute();

compiled.SetConstant("n", 9);
var result4 = (double)compiled.Execute();

Operators

The operators currently supported in order of precedence are -

[
	['!'],  // Factorial
	['**'],  // power
	['/', '*', '%'],
	['+', '-'],
	['<<', '>>'],  // bit shifts
	['<', '<=', '>', '>='],
	['==', '=', '!='],   // equality comparisons
	['&'], ['^'], ['|'],   // bitwise operations
	['&&'], ['||']   // logical operations
]
