Why is this the case? As explained later, it should not behave like <= for numbers Java String compareToIgnoreCase() The above is fine for key values that are inexpensive to compute from the values being sorted. The StringComparer returned by the OrdinalIgnoreCase property treats the characters in the strings to compare as if they were converted to uppercase using the conventions of the invariant culture, and then performs a simple byte comparison that is independent of language. Because clojure.string is a standard Clojure namespace, a deps.edn file containing only an empty map is sufficient for this activity: (ns my-hiccup (:require [clojure.string :as string])) Here are the smaller functions that .
