==Description==
*This function gives the value of pi.
*The pi is a mathematical constant with a value approximate to 3.14159.
*It is denoted by the Greek letter <math>\Pi</math>.
*<math>\Pi</math> is commonly defined as the ratio of a circle's circumference C to its diameter d.
*So <math>\Pi =\frac {C}{d}</math>, the ratio <math> \frac {C}{d}</math> is constant, and it is not considering the circle's size.
*<math>\Pi</math> is a transcendental number and irrational number.
*Being an irrational number,<math>\Pi</math> cannot be expressed exactly as a ratio of any two integers .
* But we can express as the fraction <math>\frac {22}{7} is approximate to the π value , also no fraction can be its exact value.
==Examples==
#Pi()=3.141592653589793
#Pi()/4=0.785398163
#Pi()/180=0.017453293
#Pi()/(22/7)=0.999597663
#Pi()*(5^2)=78.53981634(Area of circle with r=5)
#2*Pi()*5=31.41592654(Circumference of a cidcle with r=5).
