<li><cite>The accuracy of the floating-point operations and of the library
functions in </cite><code><math.h></code><cite> and </cite><code><complex.h></code><cite> that return floating-point
results (5.2.4.2.2).</cite>
<li><cite>The rounding behaviors characterized by non-standard values
of </cite><code>FLT_ROUNDS</code><cite>
(5.2.4.2.2).</cite>
<li><cite>The evaluation methods characterized by non-standard negative
values of </cite><code>FLT_EVAL_METHOD</code><cite> (5.2.4.2.2).</cite>
<li><cite>The direction of rounding when an integer is converted to a
floating-point number that cannot exactly represent the original
value (6.3.1.4).</cite>
<li><cite>The direction of rounding when a floating-point number is
converted to a narrower floating-point number (6.3.1.5).</cite>
<li><cite>How the nearest representable value or the larger or smaller
representable value immediately adjacent to the nearest representable
value is chosen for certain floating constants (6.4.4.2).</cite>
<li><cite>Whether and how floating expressions are contracted when not
disallowed by the </cite><code>FP_CONTRACT</code><cite> pragma (6.5).</cite>
<li><cite>The default state for the </cite><code>FENV_ACCESS</code><cite> pragma (7.6.1).</cite>

and classifications, and their macro names (7.6, 7.12).</cite>

<li><cite>Whether the "inexact" floating-point exception can be raised
when the rounded result actually does equal the mathematical result
in an IEC 60559 conformant implementation (F.9).</cite>
<li><cite>Whether the "underflow" (and "inexact") floating-point
exception can be raised when a result is tiny but not inexact in an
IEC 60559 conformant implementation (F.9).</cite>
