Webbgamma function, generalization of the factorial function to nonintegral values, introduced by the Swiss mathematician Leonhard Euler in the 18th century. For a positive whole number n, the factorial (written as n !) is defined by n! = 1 × 2 × 3 ×⋯× ( n − 1) × n. For example, 5! = 1 × 2 × 3 × 4 × 5 = 120.
