public static double Erf( double x )
Public Shared Function Erf ( x As Double ) As Double
public: static double Erf( double x )
static member Erf : x : float -> float
The error function can be defined as a Gaussian integral.
The area under a bell curve (NormalDistribution) within ∓z standard deviations of the mean is given by erf(z/√2).
For large values of x, erf(x) ≈ 1 to within floating-point accuracy. To obtain accurate values of erfc(x) = 1 - erf(x) in this range, use the Erfc(Double) function.
The inverse of the error function is available as InverseErf(Double).
