Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

Perhaps it is just me that is bugged by this, but I can never get the N function to work in Mathematica.

For example, try doing:

N[6.50889261991, 2]

and you get:

6.50889

Which clearly isn't to 2 significant figures or decimal places...

Does anyone know if there is something I am doing wrong with N?
