public final class Erfc extends Object

static double |
value(double x)
Returns the complementary error function.

public static double value(double x)
The value returned is always between 0 and 2 (inclusive).
The appropriate extreme is returned when erfc(x)
is
indistinguishable from either 0 or 2 at double
precision.
Special cases:
> 28
, then the result is 0.
< 6
, then the result is 2.
