          Library
              math
          Syntax
              math.erf(x)
Description
              The math.erf function returns the value of the error function (also called the Gauss error function ) for a given x value.
The error function is given by the following expression:
And its graph is the following:

Parameters
              - x: Value for which we want to obtain the Gauss error function.
 
Result
              The math.erf function returns a real number.
Examples
          We can obtain the value of the Gauss error function for the point x = 0.5 with the following code:
math.erf(0.5)
0.5204998778130465
