R16LIB
A Quadruple Precision Real Arithmetic Utility Library


R16LIB is a FORTRAN90 library which contains a number of utility routines using "R16" or "quadruple precision real" arithmetic.

At the moment, the status of quadruple precision real data in FORTRAN is somewhat vague. This library is very small, and right now is simply a bag containing the occasional results of forays into the world of quadruple real precision.
