Default behavior is exact

?$Post
$Post is a global variable whose value, if set, is applied to every output
expression."
$Post=N;
{E, Pi, GoldenRatio}
{2.71828, 3.14159, 1.61803}
Restore default behavior to exact using
$Post=.
{E, Pi, GoldenRatio}
{\[ExponentialE], ?, ?}
%//N
{2.71828, 3.14159, 1.61803}
