The only one that I am aware of is the greek letter pi: π.
There are many approximations, such as 3.14 or 3.14159 or 22/7. There are many functions whose solutions involve pi and so can be used to calculate pi. There are also many infinite series that converge to pi or some function of pi. Some are given in the attached link. However, these are all approximations to pi.

Is the number pi endless?
YES! the number pi is endless
Is 0.16 pie a rational number?
(pi) itself is an irrational number. The only multiples of it that can be rational are (pi) x (a rational number/pi) .
Why is pi a rational number?
Pi is irrational.
How many seconds are in the number Pi?
None, the Number Pi is nothing to do with seconds (time).
2pi is an integer?
2 times pi is not an integer. Since Pi is an irrational number, 2 pi is also an irrational number.
Does pi represent a finite or infinite number?
Pi is an irrational number. As such, it has an infinite number of digits.
What do we use the pi symbol to represent a number?
Because pi is an irrational number that has an infinite amount of digits
Is pi a number?
Technically pi is two letters put together to form a word. How ever, the word "pi" does represent the number 3.14159265... (or simply 3.14).
Can pi be negative?
No. Pi is a set number, if it were negative (-3.14159...) it would not represent the ratio of radius to circumference.
What does the Greek letter pi represent?
The number 22/7=3.14159
What are 10 different ways to write pi?
They are as follows:- 3.1 3.14 3.141 3.1415 3.14159 3.141592 3.1415926 3.14159265 3.141592654 Or as a fraction 22/7 approximately Note that there are billions and billions of ways to write out pi as number because it is an irrational number.
In math why does pi represent 3.14?
Pi does not represent 3.14. Pi represents the ratio of the circumference of a circle to its diameter. Pi is an irrational number. 3.14 is but the crudest approximation of pi. A better approximation is 3.1416. Still better is 3.14159. The closest approximation commonly used in real-world applilcations is 3.14159262. If anything, 3.14 represents pi, and represents it very imprecisely. As for why the term "pi" was chosen to represent this important concept in mathematics, it was chosen because it is the initial letter of the greek word for "perimeter".
What are 3 different ways to write pi?
the symbol itself. 22/7 3.14159.....
Why is a fraction of pi better then the decimal of pi?
Since pi is an irrational number it is impossible to represent the exact quantity as a decimal; you can only give and approximate value. However, if you write a fraction that includes the symbol for pi, you are giving an exact quantity.
What is the value of math pi?
Pi is an irrational number, which means that it goes on forever without repeating. So I can't really give you the exact value. However, there are several ways of calculating pi. in terms of a circle: Pi = Circumference/Diameter for more complicated ways of calculating pi, I would suggest looking at the wikipedia page http://en.wikipedia.org/wiki/Pi
Pi is composed of exactly how number system?
It is not clear what this question is about. The number pi is not composed of any number system. Even though the digits will be different, pi is a constant which will have the same value whatever the number system: decimal, binary, octal, et cetera.
How many significant figures in pi 3.14159...?
"Pi" is an irrational number. No series of digits can represent its value exactly, whether written as a fraction or as a decimal. The decimal can be extended to any number of significant figures, no matter how large, and never ends.
