Simply put, pi is weird. Mathematicians call it a "transcendental number" because its value cannot be calculated by any combination of addition, subtraction, multiplication, division, and square root extraction.
π is an irrational number, meaning that it cannot be written as the ratio of two integers. Fractions such as 22/7 and 355/113 are commonly used to approximate π, but no common fraction (ratio of whole numbers) can be its exact value.
The Mystery number is defined as a number which we get by sum up of two the numbers and that two numbers should be the reverse of each other, this is a unique number, to find that number must be of two digits, then break the number into two numbers such as 'A' and 'B', if the digit of 'A' is reverse of 'B' or the digit ...
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."
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. In this article, we discuss how Archimedes came up with his formula. Archimedes in fact proved that 223/71 < \pi < 22/7.
In the past, many math books listed Pi as 22/7. Again, this is just an approximation but it is better than the value of 3 (actually 22/7 is closer to Pi than just writing 3.14).

It is given that value of π up to 50 decimal places as 3.14159265358979323846264338327950288419716939937510.
Denoted by the Greek letter π, this curious little number is approximately 3.14, although computers have calculated it out past 22 trillion digits and counting: 3.141592653589793238462643383279502…, a sequence never repeating, never betraying any pattern, going on forever, infinity on a platter.
There are mostly natural numbers which cannot be distinguished from each other. They are inaccessible; we briefly call them dark. It is unfamiliar and hard for mathematicians trained to believe in completed infinity to imagine a. potentially infinite set which is finite without having a last fixed element.
Kaprekar constant, or 6174, is a constant that arises when we take a 4-digit integer, form the largest and smallest numbers from its digits, and then subtract these two numbers. Continuing with this process of forming and subtracting, we will always arrive at the number 6174.
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.)
Value of Pi (π) in Fractions
The pi value in fraction is 22/7. It is known that pi is an irrational number which means that the digits after the decimal point are never-ending and being a non-terminating value. Therefore, 22/7 is used for everyday calculations.
The beauty of pi, in part, is that it puts infinity within reach. Even young children get this. The digits of pi never end and never show a pattern. They go on forever, seemingly at random—except that they can't possibly be random, because they embody the order inherent in a perfect circle.
But since then computers have calculated more digits of pi than could ever even be recited in a lifetime, let alone memorised, and now pi memorisation is only for the truly dedicated. The world champion is Akira Haraguchi, who in 2006 recited 100,000 digits of pi from memory at a public event near Tokyo.
Last time it took pi to 31.4 trillion digits. The last 100 digits of the 100 trillion pi it discovered are: 4658718895 1242883556 4671544483 9873493812 1206904813 2656719174 5255431487 2142102057 7077336434 3095295560.
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 billionth digit of pi is 9.”
How Many Digits of Pi Does NASA Use? Let's see if the number of digits matters when you're calculating something vast, like a distance in space. For most calculations, NASA uses 15 digits: 3.141592653589793.
"The 62.8 trillion digits of pi are only a side effect of testing and benchmarking our new computing infrastructure," explained Keller. "Pi has been known for centuries to a precision of several hundred digits. Even in the most precise calculations in science and engineering, a few dozen digits are enough."
If 8 is a prime number, then the 7624th digit of π is an 8.
In 1981, an Indian man named Rajan Mahadevan accurately recited 31,811 digits of pi from memory. In 1989, Japan's Hideaki Tomoyori recited 40,000 digits. The current Guinness World Record is held by Lu Chao of China, who, in 2005, recited 67,890 digits of pi.
