Following are the operations. defmacro looks a lot like defn: it has a name, an optional documentation string, an argument vector, and a bodyin this case, just nil. in the opposite order: Such short functions are often written using Clojures #() notation, where the two arguments for compare to work on, and those vectors have the same second element: cc-cmp ("cross class compare") below may be useful in such cases. Why is this the case? (##NaN) values as equal to all other numbers. It is extremely fast even for cold start. sorted-map, This function is format-tolerant and reads incomplete dates, for example, only a year. strncasecmp method can be used to compare two strings without case sensitivity. see https://docs.oracle.com/javase/tutorial/i18n/text/locale.html or the ICU4J library: http://site.icu-project.org/home/why-use-icu4j.

In Clojure, you may also use boolean comparators that return true if the first argument should come before the second argument, or false otherwise (i.e. The formatting of strings can be done by the simple format function. It should be able to compare any pair of values that can appear in your because a return value between -1 and 1 is truncated to the int 0: This also leads to bugs when comparing integer values that differ by amounts that change sign when you If your comparator is not guaranteed to be given such restricted inputs, better not to risk it. For example, if strings are displayed to the user but case is unimportant, culture-sensitive, case-insensitive string comparison should be used to order the string data.

See the "decorate-sort-undecorate" technique described in the documentation for The concatenation of strings can be done by the simple str function. The function < is a perfect example, as long as you only need to compare numbers. It is not simply (class x), because then numbers like Integer and Long would not be sorted in numeric order. Note that since lists are used to group multiple constants that map to the same expression, a vector can be used to match a list if needed.
