How can I evaluate mathematical formulas in Go?

Evaluating Formulas in Go

In a similar vein to Python's parser module, Go offers solutions for evaluating mathematical formulas within code. One notable package that addresses this need is govaluate, available at https://github.com/Knetic/govaluate.

To utilize govaluate for formula evaluation, one can follow these steps:

1. Create a new EvaluableExpression instance by passing the formula as a string.
2. Define a map containing the variable names and their respective values.
3. Evaluate the formula using the Evaluate method, passing in the variable map as an argument.

Here's an example code snippet using govaluate:

expression, err := govaluate.NewEvaluableExpression("(x + 2) / 10")
parameters := make(map[string]interface{}, 8)
parameters["x"] = 8

result, err := expression.Evaluate(parameters)

By following these steps, developers can effortlessly evaluate formulas in Go, providing a powerful method for performing mathematical calculations within their code.
