C# Math Using Exponents: Math Region Parser

David Smith

I have math project where i want to use exponential functions, scientific notation, and exponents.

Example project I have to calculate so we are on the same page. keep in mind below e is exponential, not just any exponent. How would i write this function below in C# with t

Result = X / [(B) ^ 2 * e ^ (X / 5 * B)]

Can some one point me into the right direction??????

Now to think longterm I would wether design a Region Parser, that will calculate any math function whether its scientific notation, exponentials, polynomials, etc......

Accepted answer
The System.Math class contains a number of mathematical functions including an exponential function:

Assuming that B is a double variable, the expression you want to evaluate could be expressed as follows in C#:

double Result = X / (B * B * Math.Exp (X / 5 * B));

Unfortunately, C# doesn't currently have an 'eval' function as such.

However, there are some third party including this one, which can deal with various functions as well as basic arithmetic:

Thanks,

Now is there a region parser or project, that will basically solve in math equations. Basically doing the job of ti-89 or graphical calculater, base on user input expression.
