for NAS FortranPlus

by Alan Miller

• quad_nas.f90 Module for quadruple precision arithmetic using operator overloading.
• There is a short test program t_quad.f90, for testing the basic arithmetic operations (+-*/), and other test programs t_cubert.f90, t_cst.f90, t_logexp.f90 and t_arc.f90,for testing logs, exponential and trigonometric functions.
• qcomplex.f90 Module for complex arithmetic in quadruple precision.
• q_cpoly.f90 The classic Jenkins/Traub algorithm for finding the zeroes of a polynomial equation with complex coefficients. Originally published as CACM algorithm 419.
• q_rpoly.f90 The classic Jenkins/Traub algorithm for finding the zeroes of a polynomial equation with real coefficients. Originally published as CACM algorithm 493.
• hilbert.f90 Simple program to invert a Hilbert matrix.
