Function gamma¶
function gamma(const T1 &) math¶
Returns the approximate gamma function of an argument.
Uses a rational approximation (Lanczos-like) valid for positive real arguments. The result is an approximation, not the exact value.
| T1 | Scalar numeric type. |
| x | Argument to the gamma function. |
| Approximation of Gamma(x), as a floating-point value. |
Fully qualified name: kfr::gamma(const T1 &)
