I must be missing something here, because when I look at https://www.netlib.org/misc/intel/ which is linked from https://www.intel.com/content/www/us/en/developer/articles/tool/intel-decima... I don't see anything architecture-specific in the library, everything looks like portable C. I'm also not sure why this library would be so much faster, because the number format seems to be standard IEEE BID https://github.com/featuremine/IntelRDFPMathLib/blob/edda5420528167b14b775cc... https://github.com/featuremine/IntelRDFPMathLib/blob/edda5420528167b14b775cc... and when I look at the comparison https://github.com/featuremine/IntelRDFPMathLib/blob/edda5420528167b14b775cc... I see nothing that could possibly explain an order of magnitude difference in performance. Am I looking at the wrong thing?
