public static double DiLog( double x )
Public Shared Function DiLog ( x As Double ) As Double
public: static double DiLog( double x )
static member DiLog : x : float -> float
The dilogarithm can be defined by an infinite sum.
The function gets is name from the similarity of this series to the expansion of ln(1-x), the difference being that the integer in the denominator is raised to the second power.
Li2(x) is real for -∞ < x ≤ 1; for values outside this range, use the complex version DiLog(Complex).
