A ClojureScript port of clojure.java.math
This can be included in deps.edn by adding the following entry to the :deps map:
com.github.quoll/cljs-math {:git/tag "v0.1.2" :git/sha "e9abd32"}
The prime focus on this library is correctness before performance. It matches clojure.java.math as closely as possible.
Tests are run on both the JVM and through a connection to ClojureScript running on Node. For this reason, the file is .cljc rather than .cljs.
Testing performs generative tests, directly comparing the results of this implementation and the implementations in java.lang.Math. Fortunately, the floating point representation on both platforms conforms to IEEE-754, which validates this comparison.
Only the JavaScript Math.sin() function is compared to the equivalent Java function, to check that built-in functions have been wrapped the same way. Some built-in functions JavaScript functions have slightly less precision than the equivalent Java function, so the variance between differing answers will be displayed.
To run the tests entirely in Java, run:
clj -X:testMy hope is that this will be accepted by ClojureScript. If it is, then the Java tests may be dropped. This would allow the primary file to be renamed to .cljs and the namespace updated to clojure.math.
