Class IndyMath

java.lang.Object
org.codehaus.groovy.vmplugin.v8.IndyMath
public class IndyMath extends Object
This class contains math operations used by indy instead of the normal meta method and call site caching system. The goal is to avoid boxing, thus use primitive types for parameters and return types where possible. WARNING: This class is for internal use only. Do not use it outside the org.codehaus.groovy.vmplugin.v8 package of groovy-core.
