I asked David Hough today if the IEEE 754 committee had considered
the questions I raised about comparisons.  He said the committee
spent half of their two-hour meeting discussing my first question, but
had not yet reached a conclusion about it.   My first question was
whether a IEEE comparison operation could raise the invalid operand
exception more than once.  David said that he thinks the committee
is leaning toward allowing a comparison involving operands of
different formats to be implemented as a conversion followed by
a comparison of homogeneous operands.  Comparisons involving
operands of the same format would not be allowed to raise an
exception more than once.
