that is true, maybe because this information is missing in the help 
patch. so, when I type this number into a number box, it says 
1.67772e+07 but it still seems to work, because I can subtract 16777216 
correctly.

I separate the longitude values at the comma, which means this number 
(16777216) has to represent a range of ~111 km which gives a precision 
of less than 0.7cm.
