At large values, this function can be approximated with the Lanczos approximation, an alternative for the Stirling approximation.
At large values, this function can be approximated with the Lanczos approximation, an alternative for the Stirling approximation. This function, equal to the square root of pi at one half*, is defined as the integral from zero to infinity of t to the power of z minus one times e to the negative t. This function is not defined for non-positive integers and is noted for the fact that this function's value at z plus one is equal to z times this functions value at z, allowing it to be defined recursively. For 10 points, name this function that provides an extension of the factorial function.
