Glossary
accuracy because it is smaller in
magnitude than the smallest
normalized value.
unordered In comparison
operations, the relation that exists
between two operands if one or
both of them is a NaN (Not-a-
Number); one is neither less than,
equal to, nor greater than the
other.
vectorization The replacement
of a section of code that contains
operations on arrays with a call to
a special library routine. The
compiler attempts automatic
vectorization when invoked with
appropriate options.
zero A floating-point value that
is represented by a sign bit, a
fraction that is all zeros, and an
exponent that is all zeros. A zero
has a magnitude less than any
denormalized value.
