Copy

public static double ErfcInv(
	double z
)

Parameters

z Double: value to evaluate.

Return Value

Double
The complementary inverse error function evaluated at given value.

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.PositiveInfinity if z <= 0.0.
returns double.NegativeInfinity if z >= 2.0.
