In short: maybe don’t round to 0% or 100% in your UI.I am not a UI expert. But I sometimes build user interfaces, and I sometimes want to render a percentage to the user. For example, something like “you’ve downloaded 45% of this file”.In my experience, it’s often better to round this number but avoid rounding to 0% or 100%.Rounding to 0% is bad because the user may think there’s been no progress. Even the smallest nonzero ratio, like 0.00001%, should render as 1%.Rounding to 100% is bad because

Routing is a fundamental part of delivering applications, but it’s often treated as an afterthought—tacked onto the caching layer and configured through complex YAML or manual click-ops.
