The value of Pi (π) is a mathematical constant that represents the ratio of a circle's circumference to its diameter.

It is an irrational number, meaning its decimal representation neither terminates nor repeats. Therefore, it cannot be expressed as an exact fraction.

However, it is commonly approximated as:

• 3.14159

While 3.14 is a common and widely used approximation, the decimal representation of pi goes on infinitely.

For higher accuracy calculations, more digits are used.
