In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666...). (To only 18 decimal places, pi is 3.141592653589793238.)
There's no end to π, it's a transcendental number, meaning it can't be written as a finite polynomial.

Six nines in pi - also known as Feynman point - is a famous mathematical coincidence.
The value of pi is approximately 3.14, or 22/7. To 39 decimal places, pi is 3.141592653589793238462643383279502884197. Pi is an irrational number, which means it is not equal to the ratio of any two whole numbers.
3.14159265358979323846264338327950288419716939937510 etc. Before you click remember - it's a byte a digit! The first 1000000 decimal places contain: 99959 0s, 99758 1s, 100026 2s, 100229 3s, 100230 4s, 100359 5s, 99548 6s, 99800 7s, 99985 8s and 100106 9s. There's one '3' before the decimal point...
“The ratio of a circle's circumference to its diameter is always the same: 3.14159… and on and on (literally!) forever. This irrational number, pi, has an infinite number of digits, so we'll never figure out its exact value no matter how close we seem to get.
The string 123456789 did not occur in the first 200000000 digits of pi after position 0. (Sorry! Don't give up, Pi contains lots of other cool strings.)
PSA: "69" first shows up in the 42nd and 43rd digits of pi. It occurs 98 times in the first 10,000 digits.
I myself once learned 380 digits of π, when I was a crazy high-school kid. My never-attained ambition was to reach the spot, 762 digits out in the decimal expansion, where it goes "999999", so that I could recite it out loud, come to those six 9's, and then impishly say, "and so on!"
In honor of Pi Day, today March 14 (represented as 3/14 in many parts of the world), we're excited to announce that we successfully computed π to 31.4 trillion decimal places—31,415,926,535,897 to be exact, or π * 1013.
Results. All this fine tuning and benchmarking got us to the one-hundred trillionth digit of π — 0. We verified the final numbers with another algorithm (Bailey–Borwein–Plouffe formula) when the calculation was completed.
Because π is irrational, it has an infinite number of digits in its decimal representation, and does not settle into an infinitely repeating pattern of digits.
We learn that we can start to write down Pi (π) = 3.141592653589….. but that we can never finish it. Pi (π) goes on forever and has no repeating pattern to its digits – it is what is called an irrational number.
And how did it get the name "pi"? It was first called "pi" in 1706 by [the Welsh mathematician] William Jones, because pi is the first letter in the Greek word perimitros, which means "perimeter." Why does "pi" deserve its own day?
Measuring the perimeters of those gave upper and lower bounds of the range containing pi. He started with hexagons; by using polygons with more and more sides, he ultimately calculated three accurate digits of pi: 3.14.
The string 42069 occurs at position 250301. This string occurs 1996 times in the first 200M digits of Pi. counting from the first digit after the decimal point.
The value of pi in decimals is non-terminating and non-recurring and is approximated to 100 decimal places as 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679. For ease of calculations, it is often approximated to 3.14.
What is the 420th digit of Pi? The last digit of the number above is the 420th decimal of Pi. As you can see, the 420th decimal of Pi is 3.
Whether the circle is big or small, the value of pi remains the same. Pi can not be expressed as a simple fraction, this implies it is an irrational number. We know every irrational number is a real number. So Pi is a real number.
But did you know those post-decimal numbers continue infinitely? Pi is an irrational number, which means it cannot be represented as a simple fraction, and those numbers cannot be represented as terminating or repeating decimals. Therefore, the digits of pi go on forever in a seemingly random sequence.
The number pi is literally infinitely long. But the number 123456 doesn't appear anywhere in the first million digits of pi. It is a bit shocking because if a million digits of pi don't have the sequence 124356, it definitely is the most unique number.
Is Pi bigger than infinity? Pi is finite, whereas its expression is infinite. Pi has a finite value between 3 and 4, precisely, more than 3.1, then 3.15 and so on. Hence, pi is a real number, but since it is irrational, its decimal representation is endless, so we call it infinite.
It is known that \pi is an irrational number and therefore cannot be expressed as a common fraction. Its value is approximately equal to 3.141592. Since Archimedes was one of the first persons to suggest a rational approximation of 22/7 for \pi, it is sometimes referred to as Archimedes' constant.
