Double Precision Complex Computation

These subprograms do the following computations for double precision complex data: sum, difference, product, quotient, square root, and absolute value. The Fortran 77 standard does not support a double precision complex data type.   Using the convention of storing the real and imaginary parts of a complex number as an adjacent pair of double precision numbers, this set of subprograms provides the above operations while staying within the standard.
This software is part of the MATH77/mathc90 collection here.
