I am once again unsuccessfully advocating for engineers to not use Excel for any engineering purpose, especially not for NUCLEAR SAFETY-RELATED WORK. It will again fall on deaf ears; we don't have a suitable replacement for easily making publication-ready plots from CSV data, it's installed everywhere by default, and engineers are going to use it regardless of risks. https://answers.microsoft.com/en-us/msoffice/forum/all/excel-truncates-and-reduces-precision-with-save-as/e57b3cbe-c04f-4199-a2fa-e908643fc3dd

I'm trying to be a kinder, gentler engineering software version of Ignaz Semmelweis here but I expect to be ignored and eventually go mad https://en.wikipedia.org/wiki/Ignaz_Semmelweis

We spend obscene amounts of time and effort ensuring our safety-related design and analysis codes correctly perform the work we need to them to perform. I have been qualifying one (1) minor R code for over a year now. I'm not the only one. All that work thrown away because Excel and engineers.

From Wikipedia: "In 1865, the increasingly outspoken Semmelweis allegedly suffered a nervous breakdown and was committed to an asylum by his colleagues. In the asylum he was beaten by the guards. He died 14 days later from a gangrenous wound on his right hand that may have been caused by the beating."

I know how this story ends.
