Wrong Precision with "N" ??

Will someone explain to this newbie why the advertised
behavior of the numerical evaluation function "N" to some
specific precision - flatly ignores the second argument?

For example, on my machine,

N[Pi,2] = N[Pi,3] = N[Pi,4] = N[Pi,10] = 3.14159

which is not at all what 'Help', and any number of books,
claim, with no explanation of why it just might not work
out that way (??)
