The INT_<op>_RANGE_OVERFLOW macros return 1 if the corresponding C
|
||||
operators might not yield numerically correct answers due to
|
||||
arithmetic overflow. They do not rely on undefined or
|
||||
implementation-defined behavior. Their implementations are simple
|
||||
and straightforward, but they are a bit harder to use than the
|
||||
INT_<op>_OVERFLOW macros described below.
|
||||
|
||||
Example usage:
|
||||
|
||||
long int i = ...;
|
||||
long int j = ...;
|
||||
if (INT_MULTIPLY_RANGE_OVERFLOW (i, j, LONG_MIN, LONG_MAX))

else

|

|
||||
Restrictions on *_RANGE_OVERFLOW macros:
|
||||
|
||||
These macros do not check for all possible numerical problems or
|
||||
undefined or unspecified behavior: they do not check for division
|
||||
by zero, for bad shift counts, or for shifting negative numbers.
|
||||
|
||||
These macros may evaluate their arguments zero or multiple times,
|
||||
so the arguments should not have side effects. The arithmetic
|
||||
arguments (including the MIN and MAX arguments) must be of the same
|
||||
integer type after the usual arithmetic conversions, and the type
|
||||
must have minimum value MIN and maximum MAX. Unsigned types should
|
||||
use a zero MIN of the proper type.
|
||||
|
||||
These macros are tuned for constant MIN and MAX. For commutative
|
||||
operations such as A + B, they are also tuned for constant B. */

See above for restrictions. */

The INT_<op>_OVERFLOW macros return 1 if the corresponding C operators

They work correctly on all known practical hosts, and do not rely

long int i = ...;

long int j = ...;

These macros do not check for all possible numerical problems or
|
||||
undefined or unspecified behavior: they do not check for division
|
||||
by zero, for bad shift counts, or for shifting negative numbers.
|
||||
|
||||
These macros may evaluate their arguments zero or multiple times, so the
|
||||
arguments should not have side effects.
|
||||
|
||||
These macros are tuned for their last argument being a constant.
