======Intro====== ====Synopsis==== This is the infinite series approximation of Pi ====Overview==== There are several key instruments that are used in this code. * A for loop handles the approximation * Math is handled iteratively through recursion. * Some things that are less apparent: * You don't need variable definitions to declare what data you are storing in a variable. * $result is being returned in plaintext on the page after generating the number * the "+" specified in the declaration of the $op variable is declaring the sign of the variable(positive). ====Operators==== "*" is used for multiplication "/" is used for division
