Rounding error in rain probability

[zekooooo]

Often when you look up the forecast for future dates, there's light rain but the probability is a number like 28.999999996% or 55.0000000001%. It extends onto the rainy cloud icon.

It shouldn't be too hard to replicate, if you check several places that are famous for rain, like Suva or London, you'll find it usually. I'm getting it right now for noon UTC tomorrow in Suva.
