Description

erfc(x) computes the complementary error function of x, defined as

1erf(x)=12π 0 xe t 2dt. 1 - \text{erf}(x) = 1 - \frac{2}{\sqrt{\pi}} \int_0^x e^{-t^2} dt.

Standard

Fortran 2008 and later

Class

Elemental function

Syntax

result = erfc(x)

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 0erfc(x)20 \leq \mathop{erfc}(x) \leq 2.

Example

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