This is the IEEE QP float number 43fefffffffffffff7ffffffffffff80 which I very much doubt is the maximum finite double-double? See the 0 in the middle of the mantissa... 43feffffffffffffffffffffffffff00 is bigger, and representable as double-double just as well? Or even 43feffffffffffffffffffffffffff80 should be. Segher
