Overview

Package math exposes JVM-faithful java.lang.Math equivalents for code running on glojure. Each symbol is published two ways:

• as a Go package-level value (used when gloat AOT-compiles a Clojure call site to a direct Go reference such as `compatmath.Sqrt`); and
• through glojure's pkgmap (used by the REPL and any dynamic resolution path).

Java's Math methods are overloaded by argument type (int, long, float, double). The polymorphic helpers here type-switch on the runtime argument and dispatch to the matching gojava overload, returning a Go value whose type mirrors what the JVM would have produced for the same call.

Types

type Math

type Math struct{}

Math is the placeholder type registered as java.lang.Math's reflect.Type. java.lang.Math is final with a private constructor in the JVM, so no instances ever exist; the value here only needs to make (instance? Class Math) succeed so (ns-imports *ns*) sees the import.
