public static double HarmonicNumber(
	double n
)

Public Shared Function HarmonicNumber ( 
	n As Double
) As Double

public:
static double HarmonicNumber(
	double n
)

static member HarmonicNumber : 
        n : float -> float

Double
The nth harmonic number.

Remarks

The harmonic number is

      n
      --
Hn =  >   1 / k
      -- 
     k = 1

The harmonic number is closely related to the digamma function. (Ref. http://mathworld.wolfram.com/HarmonicNumber.html )
