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. If the vector already has sufficient memory to accommodate all characters in the string, we can even pass the input iterator to the beginning of the vector to the std::copy algorithm, as Clojure AOT Compilation. Why is this the case? Returns a negative number, zero, or a positive number when x is logically 'less than', 'equal to', or 'greater than' y. You're better off using toLowerCase() or localeCompare() than using a regular expression. It supports Clojure 1.5.1 and later as well as ClojureScript. Return Value Returns a negative number, zero, or a positive number when x is logically 'less than', 'equal to', or 'greater than' y. The format function formats a string using java.lang.String.format. If the key values are expensive to compute, it is better to calculate them once for each value. 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. Same as Java x.equals(y) except it also works for nil, and compares numbers and collections in a type-independent manner.

Java comparators must return a 32-bit int type, so when a Clojure function is used as a comparator and it returns any type of number, that number is converted to an int behind the scenes using the Java method intValue. Has 90% of ice around Antarctica disappeared in less than a decade? For example, the below comparison fails, whereas it would succeed using toLowerCase() or localeCompare(). In our case, we will check if the return value is 0 or not. Following is an example of the string formatting in Clojure. It is less error-prone to use explicit conditional checks and return -1, 0, or 1, or to use boolean comparators. numbers in decreasing order.
