PIGEN (NumberOfIterations)

Description

This function is showing the value of pi with some didgits.
In $PIGEN(NumberOfIterations)$ , $NumberOfIterations$ is any number.
The pi is a mathematical constant with a value approximate to 3.14159.
It is denoted by the Greek letter $\pi$ .
$\pi$ is commonly defined as the ratio of a circle's circumference C to its diameter d.
So $\pi$ = ${\frac {C}{d}}$ , the ratio ${\frac {C}{d}}$ is constant, and it is not considering the circle's size.
$\pi$ is a transcendental number and irrational number.
Being an irrational number,π cannot be expressed exactly as a ratio of any two integers ,but we can express as the fraction 22/7 is approximate to the $\pi$ value.
Also no fraction can be its exact value.
This function is showing the $\pi$ value generally with nearly 40 decimals.
