Day 6: Wait for It

Megathread guidelines

Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
Code block support is not fully rolled out yet but likely will be in the middle of the event. Try to share solutions as both code blocks and using something such as https://topaz.github.io/paste/ , pastebin, or github (code blocks to future proof it for when 0.19 comes out and since code blocks currently function in some apps and some instances as well if they are running a 0.19 beta)

(number+1).floor() does the trick

Oh yeah, that's clever. I'll remember that when it comes up again.

In Python when using numpy to find the roots, sometimes you get a numeric artifact like 30.99999999999, which breaks this. Make sure to limit the significant digits to a sane amount like 5 with rounding to prevent that.
