Follow-up Comment #11, bug #61788 (project octave): Most (or all?) platforms that Octave supports use two's complement for signed integer. Could we use the overflow behavior of (un)signed C integers to make this work? http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf §6.2.5 9: > A computation involving unsigned operands can never overflow, because a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting type. We could extend that specification to signed integers if we assume two's complement... _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?61788> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
