Is there anybody know how to calculate ERFC in Fortran 77?

ERFC is a mathematical function used in Fortran 77 to calculate the complementary error function. It is denoted by ERFC(x) and is defined as 1-ERF(x), where ERF(x) is the error function.
To calculate ERFC in Fortran 77, you can use the built-in function ERF or the complementary error function subroutine, depending on your specific requirements. Both methods require the input of a real number, x, and will return the value of ERFC(x).
The main difference between ERFC and ERF in Fortran 77 is that ERFC calculates the complementary error function (1-ERF), while ERF calculates the error function. As a result, the outputs of these two functions are complementary to each other.
Yes, ERFC in Fortran 77 is commonly used in various fields of science and engineering, such as statistics, physics, and telecommunications. It can be applied to problems involving the probability of errors, signal processing, and solving differential equations, among others.
One limitation of using ERFC in Fortran 77 is that it only accepts real numbers as input. This means that it cannot be used to calculate the complementary error function for complex numbers. Additionally, the accuracy of the output may be affected if the input is too large or too small.
