Happy pi day!
The number represented by ‘pi’ is a mathematical constant that is the ratio of a circle’s circumference to its diameter, approximately equal to 3.14159.
It is an irrational number, meaning that it cannot be expressed exactly as a ratio of two integers, although fractions such as ‘22/7’ are commonly used to approximate it.
Consequently, its decimal representation never ends, nor enters a permanently repeating pattern. It is a transcendental number, meaning that it cannot be a solution of an equation involving only sums, products, powers, and integers.
