I don't understand. As far as I can see '%.2f' % 2.545 is returning
the correct result: there is no bug here, so no need to reopen. '%.2f'
should *not* return 2.55; it should return 2.54, which is exactly what it
does. round(2.545, 2) should also return 2.54, but returns 2.55 instead;
issue 1869 is already open for this.
You're correct that the float formatting doesn't use round: it does
whatever the platform C library's sprintf does.
