There does not seem to be a specific call for ABS on Int(1) types. 1. Which is the best ABS name to use for int*1? 2. ABS doc says ABS arg is real so what happens when I feed it int(4) or int(1)
No speed difference at all - you get the same code (inline instructions in this case). Specific names are a holdover from Fortran 66 - their only legitimate use in modern Fortran is when passing them as arguments to other routihnes.
