The ceiling-division idiom `(n + d - 1) / d` only produces the
correct result when `n` is non-negative.
For example, if n = -1000 (exactly -1us), the old code computed (-1000
+ 999) / 1000 == 0 instead of -1.
For negative n, truncating division already rounds towards positive
infinity, so no bias is needed in that case.
