Interface

ErrorFnC

The complementary error function, usually denoted as erfc is directly related to the Error Function by:

errorFnC(x) = 1 -  errorFn(x)

Thus It therefore has the following shape:

Example 1

#include <codecogs/maths/special/errorfnc.h>
#include <stdio.h>
using namespace Maths::Special;
int main()
{
  double x = 0.5;
  printf("\n errorFnC(%f) = %f", x, errorFnC(x));
}

Output:

errorFn(0.500000) = 0.479500
