The value of the result is an approximation to the “complementary error function” of X; that is mathematically equal to 1.0−ERF(X).
Like many intrinsic functions, this is elemental; the result has the same shape as X, with the operation being applied elementwise.
This function converges to 0.0 quickly with increasing X.
