Namespace: Altaxo.Calc
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
public static double ErfcInv(
	double z
)

Parameters

z  Double
value to evaluate.

Return Value

Double
The complementary inverse error function evaluated at given value.
Remarks
We have tested this implementation against the arbitrary precision mpmath library and found cases where we can only guarantee 9 significant figures correct.

  • returns double.NegativeInfinity if z >= 2.0.
