<Syntax> 



ERFC_SCALED ( X )
X : Real;
Result : Same type and kind as X.






<Semantics> 



The value of the result is an approximation to the exponentiallyscaled “complementary error function” of X; that is ERFC(X) scaled by e^{X**2}.
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, but only slowly.
