8.11.9.95 ErFC Intrinsic

ErFC(X)

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

X: REAL; scalar; INTENT(IN).

Intrinsic groups: unix.

Description:

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.
