A data storage company has decoded more than 100 trillion digits of pi — smashing the world record for calculating the never-ending number. Unraveling this hefty slice of pi required the equivalent computing power of hundreds of thousands of smartphones.
Pi — often abbreviated as 3.14 — is an irrational number, meaning it has infinite nonrepeating decimal places. The value of pi is equal to the circumference of a circle (the distance around its edge) divided by its diameter (the distance between two directly opposite points). It means you can figure out the circumference of any circle if you know its diameter or radius (half the diameter) or vice versa because we know the value of pi.
