Sprint Days Remaining Gadget shows apparently too few days

Expected:

Days Remaining should reasonably portray the amount of time remaining to accomplish the sprint, i.e., via rounding.

Actual:

The Sprint Days Remaining gadget appears to calculate via flooring, which is misleading/confusing. (This change appears to have happened in a recent update.) In particular, every day at morning standup, the remaining days appears to be 1 fewer than actually available.
