NCalc | GitHub clone of NCalc from http : //ncalc.codeplex.com/

I have a dynamic formula that needs calculation.

Here's a sample (var1 * var2) / (var3 * (23 * 100))

These variables will be replaced with actual numbers because they are user input. Currently, I am using power automate flow that connects to my web API to throw any calculation and solve it. then send back the result. I am using NCalc and/or DataTable on the API.

What I was hoping to do was to pass the calculation in any Control like label or text. If you put 1+1 to the Text property of a Label Control. It will show the number 2 right away but since I am passing string it doesn't work. I can use something like this Value("100" * "300") and this works as long as we stick with math operators only but fails when we have the open and close parentheses like this (21 * 100) / (0.43 * (23 * 100))

I will appreciate it if you have a workaround in mind. Thank you in advance.

I need this to loop from -n to n but this only produces one co-ordinate so far. Does anyone know any easy quick fixes so I can have values from -n to n (step 1) subbed into the y equation id input?

I'm also not sure if I'm using the expression section correctly as I've never tried NCalc before today.

I have made the corrections suggested by Craig Estey. The code now compiles and work. This is the revised code:

I'm working on financial app, so I care about accuracy and I need to evaluate formula expression like:

  I am trying to write a simulation where different threads need to perform a given calculation on a thread-specific interval (in the minimal example here that interval is between 1 and 4) based on an atomic simulation time managed by a parent thread.

  The idea is to have the parent advance the simulation by a single time step (in this case always 1 for simplicity) and then have all the threads independently check if they need to do a calculation and once they have checked decrement an atomic counter and wait until the next step. I expect that after running this code the number of calculations for each thread would be exactly the length of the simulation (i.e. 10000 steps) divided by the thread-specific interval (so for thread interval of 4 the thread should do exactly 2500 calculations.

I want to calculate a string in C# using either NCalc or DynamicExpresso library, the problem is, when the calculation gets complex and the numbers are big, it returns the wrong result. For example the code below returns -808182895 when it should return 3486784401

Everytime I attempt to copy Brevity.Api.xml, it'll always end up with a 'Not found' issue and would cause build failures. Listing the files in the directory of the where the docker build is at before executing the copying instructions show that the file is indeed there. What am I missing? Check step 11 (At the bottom of the log) in the build log

Example a: √12 =2√3

Example b: √16 = 4

I am trying to get both.

Whilst I can of course use Math.Sqrt(4) to achieve outcome b, I've no idea how to achieve a, or further how to get both to work simultaneously which is the goal. How do I achieve this type of simplification in C#?

I have tried several libraries including MathNet, Symbolics and NCalc with no success. This post may have solved it in c++, although I do not know for sure. My attempts at converting that solution to even see if it worked were very much a failure:

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?
