STORY OF PI (Ï€)
Pi (Ï€) is defined as the ratio of the circumference of a circle to its diameter. There is no such thing as its exact value because it is a non-terminating non-recurring decimal number,which when simply put means that its value has no end. It is also referred as a TRANSCENDENTAL NUMBER, and more importantly it is an irrational number(like √2 ,√3 ...).
The decimal representation of pi(Ï€) has an approximate value of 3.14,which we take normally for many calculations in general math.
The first 100 significant figures of π are
Ï€ = 3.14159265358979323846264338327950288419716939937510582097
4944592307816406286208998628034825342117067... ... (the laundry list continues forever)
The fractions 22/7, 355/113 approximate to its value(but still not exact).
355/113 = 3.14159292 (accurate up to six digits)
22/7 = 3.142857143 (accurate only up to two places)
For general purpose calculations 22/7 is taken as π [close but not close enough :-)]
