c8lib

**c8lib**,
a Fortran90 code which
implements certain
elementary functions for double precision complex (C8) variables.

The symbol "C8" is used to suggest a double precision complex
variable. Here the 8 indicates that the underlying pair of
real numbers each use 8 bytes of storage.

C8LIB contains routines that operate on scalars, vectors or
doubly dimensioned arrays of C8's. A vector of C8's is denoted
a C8VEC, and a doubly dimensioned array is a C8MAT.
