Gamma.lanczos介绍

[英]Returns the Lanczos approximation used to compute the gamma function. The Lanczos approximation is related to the Gamma function by the following equation gamma(x) = sqrt(2 * pi) / x * (x + g + 0.5) ^ (x + 0.5), where g is the Lanczos constant.
[中]返回用于计算gamma函数的Lanczos近似值。Lanczos近似与Gamma函数相关，通过以下方程式Gamma（x）=sqrt（2pi）/x（x+g+0.5）^（x+0.5），其中g为Lanczos常数。
