There is a mismatch between the terminology of XSD 1.1 part 2 regarding
precisionDecimal, and the terminology of IEEE 754 - 2008. In particular, the
term "precision" is used in a quite different way. In XSD 1.1 it is used to
mean (essentially) the exponent when the significand is treated as an integer,
while in IEEE it is used to mean the (maximum) number of digits in the
significand.
