Error // ReverseByteOrder ( "EEFF" ) => FFEE Let( L = Length( bytes ) ; Case( Filter ( Upper( bytes ) ; "0123456789ABCDEF" ) ≠ bytes ; Evaluate("Factorial(-1)"); L = 2 ; Upper( bytes ) ; Mod( L ; 2 ) ≠ 0 ; Evaluate("Factorial(-1)"); Mod( L / 2 ; 2 ) = 1 ; ReverseByteOrder( Middle( bytes ; 3 ; L ) ) & Upper( Left( bytes ; 2 ) ) ; ReverseByteOrder( Middle( bytes ; L / 2 + 1 ; L ) ) & ReverseByteOrder( Left( bytes ; L / 2 ) ) ) ) Click to copy
