   ROTFL.  Intent to column 7 and the following worked over 66 years ago.   
      
   program real_kinds   
      real x   
      fraction(x) = mod(x,1.)   
      x = 3.12345   
      print *, fraction(x)   
   end program real_kinds   
      
   % gfcx -o z a.f90 && ./z   
     0.123450041   
      
      
   So, how is a user without looking at the documentation   
   to know what modf()?
