public static double value(double x)
This implementation computes erfc(x) using the
regularized gamma function
,
following Erf, equation (3).
The value returned is always between 0 and 2 (inclusive).
If abs(x) > 40
, then erf(x)
is indistinguishable from
either 0 or 2 at double
precision, so the appropriate extreme
value is returned.
