PaulDj,

This is because the default display precision for machine precision numbers is 6
places. You can change this is the Option Inspector, or you can use NumberForm to
displace the desired number of places. When i <= 16 you obtain a machine precision
number. When i > 16 you no longer have a machine precision number and Mathematica now
displays its set precision.

Remember that N is used to convert exact numbers to approximate numbers. It is not an
output formatting tool.
