WebMay 26, 2024 · Note that the real*8 syntax is an extension and not standard. Also with real(8) you are assuming that “real kind 8” is an 8-byte real (which conceivably isn’t even double precision), but there’s nothing in the standard that says kind values correspond to the byte size. In fact with the NAG compiler this isn’t the case. They number their kinds … WebFortran provides two more intrinsic functions to obtain the kind value for the required precision of integers and reals − selected_int_kind (r) selected_real_kind ( [p, r]) The …
