public static double value(double x)
This implementation computes erf(x) using the
regularized gamma function
,
following Erf, equation (3)
The returned value is always between -1 and 1 (inclusive).
If abs(x) > 40
, then Erf.value(x)
is indistinguishable from
either 1 or -1 at double
precision, so the appropriate extreme value
is returned.
