you get 1∡5.999999998
how do Hp explains that too?

It's essentially the same reason. Probably the number is internally stored in rectangular coordinates, i.e. in this case cos(6) +i·sin(6). Rounded to 12 digits that's 0,994521895368+0,104528463268 · i. If this is converted back to get displayed in polar coordinates you get 1∡6,00000000002. Which BTW is exactly what my HP35s returns after entering 1∡6. A tiny variation in the last digit and you may also get 5,99999...

Let us never forget: if you type sqrt(2) you will not get sqrt(2) but 1,41421356237. Press the Pi key and you will not get Pi but 3,14159265359. It's always just an approximation with 12 valid digits. If you're lucky. ;-)
