ErFC Intrinsic


ErFC: REAL function, the KIND= value of the type being that of argument X.

X: REAL; scalar; INTENT(IN).

Intrinsic groups: unix.


Returns the complementary error function of X: ERFC(R) = 1 - ERF(R) (except that the result might be more accurate than explicitly evaluating that formulae would give). See erfc(3m), which provides the implementation.
