> FORTRAN has a REAL16 type Fortran (note the post-'77 spelling) doesn't. It has KINDs. REALx is a non-standard extension, and there's definitely no requirement to implement 128-bit floating point. I don't know what hardware other than POWER has hardware 128-bit FP (both IEEE and IBM format, with a somewhat painful recent change of the ppc64le ABI default in GCC etc.). |
