For several of my goals, I am measuring units of work which must be entered as integers (e.g. changing my dyson vacuum filters, calling my uncle, or ice cubes fed to my orchid).

Beeminder doesn't know I can't do less than 1 of these, so it tells me that I need to call my uncle 0.0011 times in the next 18 days, or that I need to change my vacuum filters 0.011 times in the next 9 days.

With the setting I am suggesting, Beeminder would display "1 in the next X days" for these types of goals.
