“The accuracy of the floating-point operations and
of the library functions in <math.h> and
<complex.h> that return floating-point results (C90
and C99 5.2.4.2.2).” |
|
The accuracy is unknown. |
“The rounding behaviors characterized by
non-standard values of FLT_ROUNDS (C90 and C99
5.2.4.2.2).” |
|
No such values are used. |
“The evaluation methods characterized by
non-standard negative values of FLT_EVAL_METHOD (C90 and C99
5.2.4.2.2).” |
|
No such values are used. |
| “The direction of rounding when an integer is
converted to a floating-point number that cannot exactly represent the original
value (C90 6.2.1.3, C99 6.3.1.4).” |
|
The integer is rounded to the nearest floating-point
representation. |
| “The direction of rounding when a floating-point
number is converted to a narrower floating-point number (C90 6.2.1.4,
6.3.1.5).” |
|
A floating-point number is rounded down when converted to a narrow
floating-point value. |
| “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 (C90 6.1.3.1, C99
6.4.4.2).” |
|
Not applicable; FLT_RADIX is a power of 2. |
“Whether and how floating expressions are
contracted when not disallowed by the FP_CONTRACT pragma (C99
6.5).” |
|
The pragma is not implemented. |
“The default state for the
FENV_ACCESS pragma (C99 7.6.1).” |
|
This pragma is not implemented. |
| “Additional floating-point exceptions, rounding
modes, environments, classifications and their macro names (C99 7.6,
7.12).” |
|
None supported. |
“The default state for the
FP_CONTRACT pragma (C99 7.12.2).” |
|
This pragma is not implemented. |
| “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 (C99 F.9).” |
|
The exception is not raised. |
| “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 (C99 F.9).” |
|
The exception is not raised. |
