Code:

g H.MS g H.MS ...

What is the reasoning behind this sequence?

The first →H.MS reduces the fractional part to less than 0,6 and after the second →H.MS it's below 0,36. This way the rounding procedure always rounds down to the next lower integer. You could just as well use [.] [5] [–], but [→H.MS] [→H.MS] is one step shorter. ;-)

BTW, this method still is not perfect. It works up to x = 8E+9.
