Read more about parameters of erfc in parameters section

The erfcfunction in C language Calculates the complementary error function of the specified number.

The erfc function computes the complementary error function of x. The complementary error function is defined as erfc(x) = 1 - erf(x), where erf(x) is the error function. However, erfc is often more accurate than calculating 1 - erf(x) directly, especially for large values of x. This function is commonly used in various statistical computations.

The erfcfunction takes 1 parameter:

•
double `x`: The input value for which the complementary error function is computed

Computes the complementary error function of the given value `x`. The complementary error function is defined as 1 - erf(x) and is used in statistics, probability theory, and error analysis.

The erfc function return value :

Returns the complementary error function value of x
The return value is always in the range [0, 2]

Output

This example demonstrates the basic usage of the `erfc` function for various input values, showing how the complementary error function behaves for negative, zero, and positive inputs.
