Bug ID: 105905
Summary: A possible rounding error
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zhonghao at pku dot org.cn
Target Milestone: ---
magnum is a data visualization library. I notice that its programmers
complained a rounding error in gcc. It occurs when compiling their code in the
release version. To fix the problem, they change their test cases, which is a
workaround:

I also open an issue in magnum. Its programmers can provide more feedback.
