ALog – Archaic form of LOG() – FORTRAN

In older versions of Fortran, the logarithm function was typically called using the function ALOG().

However, it is important to note that the ALOG() function is considered archaic and is no longer recommended for use in modern Fortran programming.

In modern Fortran, the logarithm function is called using the LOG() function. This function allows you to calculate the logarithm of a number with a specified base.

program logarithm_example
  real :: x, result

  x = 10.0
  result = LOG(x)

  write(*,*) "The logarithm of", x, "is", result

end program logarithm_example

Output

   
 The logarithm of   10.0000000     is   2.30258512
