📦 Be sure to check out the NuGet pacakge: https://www.nuget.org/packages/NTDLS.ExpressionParser

ExpressionParser is a mathematics parsing engine for .net. It supports expression nesting, custom variables, custom functions all standard mathematical operations for integer, decimal (floating point), logic and bitwise.

It addition to the custom functions and variables, these are built in: ACOS, ASIN, ATAN, ATAN2, LDEXP, SINH, COSH, TANH, LOG, LOG10, EXP, MODPOW, SQRT, POW, FLOOR, CEIL, NOT, AVG, SUM, TAN, ATAN, SIN, COS, ABS.

If you can for the C++ verison you can find it at: https://github.com/NTDLS/CMathParser

Basic example usage:

Be sure to check out the NuGet pacakge: https://www.nuget.org/packages/NTDLS.ExpressionParser/

Simple example:

In this example we will create an expression that uses two built in functions "Ceil" and "Sum", a custom function called "DoStuff" and one variable called "extra". You can also pass a configuration parameter to set max memory size, cache scavange rate and partition count.

var expression = new Expression("10 * ((5 + extra + DoStuff(11,55) + ( 10 + !0 )) * Ceil(SUM(11.6, 12.5, 14.7, 11.11)) + 60.5) * 10");

//Add a value for the variable called "extra".
expression.AddParameter("extra", 1000);

//Handler for the custom function:
expression.AddFunction("DoStuff", (double[] parameters) =>
	double sum = 0;
	foreach (var parameter in parameters)
		sum += parameter;
	return sum;

var result = ExpressionParser.Evaluate(expression);
