ERFC — Error function

ERFC(X) computes the complementary error function of X.

RESULT = ERFC(X)

X The type shall be REAL.

The return value is of type REAL and of the same kind as X. It lies in the range 0 \leq erfc (x) \leq 2 .



program test_erfc

  real(8) :: x = 0.17_8

  x = erfc(x)

end program test_erfc
