Is there an equivalent of DEXP for complex*16 arguments in Fortran?

Question

As stated in the question : Is there an equivalent of DEXP for complex*16 arguments in Fortran (90 and later)?

Answer 1

complex*16 isn't Fortran (90 or earlier or later). If your data type is complex(real64) (or the non-standard complex*16) the standard generic exp() will select the corresponding precision and range.
