• In , is any number.
• The pi is a mathematical constant with a value approximate to 3.14159.
• It is denoted by the Greek letter .
• is commonly defined as the ratio of a circle's circumference C to its diameter d.
• So =, the ratio is constant, and it is not considering the circle's size.
• 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 value.
• Also no fraction can be its exact value.
• This function is showing the value generally with nearly 40 decimals.
