Rounding inconsistency

[villebro]

When formatting 11999 milliseconds using default options, the result is 1m 60s (should obviously be 2m). Looking at the unit tests I also didn't quite understand why seconds round down

	t.is(prettyMilliseconds(33333, {secondsDecimalDigits: 0}), '33s');

but milliseconds round up:

	t.is(prettyMilliseconds(33.333, {millisecondsDecimalDigits: 0}), '34ms');

Is there some reason why seconds round as we expect them to (mathematically), but milliseconds seem to round up?

Good catch.

Not that I can think of. It should really use Math.round() instead of Match.ceil().
