The next digit would be a 3; in any case, though, there is no reason to round the 2 down to a 1. Thanks to Bryan O'Sullivan for pointing this out. People cannot use Emacs to reliably calculate the circumference of the universe until this is fixed.

Type ESC ESC and enter the more precise value; it will be echoed to you as the less precise one.
