`nagfor` 7.1 supports half-precision floating-point numbers, but with many bugs

5

Update (20240307):

  1. nagfor 7.1 Build 7149 released on March 5, 2024, fixed all the above four bugs, but introduced an ICE when compiling PRIMA. The ICE has nothing to do with half-precision real, because it occurs even if PRIMA is configured to use single or double precision.
