o SQRT-QD has round-off problems for very large and very small numbers. Solve this by scaling the number by a power of 4 before computing the square root. o Moved LOGB-FINITE and the core of QD-CSSQS to this file from qd-methods.lisp. Rename the core routine as HYPOT-QD. o Use it in ATAN-QD/NEWTON to get rid of unnecessary overflow. qd-methods.lisp: o Moved LOGB-FINITE and the core of QD-CSSQS from this file to qd-fun.lisp. Use HYPOT-QD in QD-CSSQS. qd-package.lisp: o Export HYPOT-QD.
