Double-quad precision package with special functions

DQFUN: A double-quad precision package with special functions (approximately 66 digit precision). This package permits one to perform floating-point computations (real and complex) to double-quad precision (approximately 65 digits), by making only relatively minor changes to existing Fortran programs. All basic arithmetic operations and transcendental functions are supported, together with numerous special functions. The package should run correctly on any Unix-based system supporting a Fortran-2008 compiler and IEEE 128-bit floating-point arithmetic (in hardware or software).
