How to Evaluate Mathematical Formulas in Go?

Evaluating Formulas in Go

To evaluate mathematical formulas in Go, it's recommended to use an external package that provides pre-defined functions and operators. One popular option is govaluate:

• Installing govaluate:

  go get github.com/Knetic/govaluate

• Formula Evaluation:

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

In the above example:

• NewEvaluableExpression: Creates an instance of EvaluableExpression that represents the formula.
• parameters: A map that specifies the values to be used for the variables in the formula.
• Evaluate: Evaluates the formula using the specified parameters and returns the result as a float64.
