- Fix false positive when divisor is a real number. - Fix false negative when divident is real, but divisor is complex. - Fix false negative when due to promotion the division is performed in higher precision than the divident. - Fix false negative in divide and assign (`a /= b`). Fixes: #131127 --------- Co-authored-by: Zahira Ammarguellat <zahira.ammarguellat@intel.com>
