It is intended as a +substitute for IEEE 128-bit quad precision on systems where quad precision is +not available. 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 +64-bit floating-point arithmetic. |
