SYNTAX
result = erfc(x)
DESCRIPTION
erfc(x) computes the complementary error function of X, defined as $$ 1 - \text{erf}(x) = 1 - \frac{2}{\sqrt{\pi}} \int_0**x e**{-t**2} dt. $$
ARGUMENTS
X - The type shall be REAL.
RETURN VALUE
The return value is of type REAL and of the same kind as X. It lies in the range
0 <= ERFC(X) <= 2.
