What would be the simplest way to evaluate/simplify a mathematical string in VB?
For example: "k*k+(5+2*5)k+k" would simplify to "k^2+15k+k" and "5^2+3" would evaluate to 28.
To evaluate, I'm using NCalc by simply using the evaluate function, but it doesn't simplify expressions. What would be the simplest way of simplifying the equations?
You could try Math.NET Symbolics.
It doesn't "know" about the implied multiplication for (a)b, so you would have to work out how to insert an * if you can't require it.
Imports MathNet.Symbolics
Imports Expr = MathNet.Symbolics.SymbolicExpression
Module Module1
Sub Main()
Dim a = Expr.Parse("k*k+(5+2*5)*k+k")
Console.WriteLine(a.ToString())
Console.WriteLine(Expr.Parse("5^2+3"))
Console.ReadLine()
End Sub
End Module
Outputs:
16*k + k^2
28
