FORTRAN 77 supports only single precsion complex (not double
precision complex).

Both PL/I and Fortran 90 support COMPLEX and double precision.

FFT algorithms in PL/I can be found in "Intro to PL/I, Algorithms, and
Structured Programming (Vowels)

FFT algorithms in Fortran can be found in Press, Teukolsky,
Vetterling, Flannery, "Numerical Recipes in Fortran".
