Description:

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

Option:

gnu

Class:

elemental function

Syntax:

X = ERFC(X)

Arguments:

X	The type shall be REAL(*), and it shall be scalar.

Return value:

The return value is a scalar of type REAL(*) and it is positive ( 0 \leq erfc (x) \leq 2 .

Example:

          program test_erfc
            real(8) :: x = 0.17_8
            x = erfc(x)
          end program test_erfc
