Pi symbol (π): copy and paste
Pi (π) is the sixteenth letter of the Greek alphabet and the mathematical constant 3.14159…, the ratio of a circle’s circumference to its diameter.
Lowercase π is the constant; capital Π denotes a product in math and statistics. In code use Math.PI (JavaScript), math.pi (Python) or PI() (spreadsheets) rather than the character.
