Imports
groovy.lang.MetaMethod, org.codehaus.groovy.GroovyBugError, java.lang.invoke.MethodHandle, .MethodType, java.math.BigDecimal, java.util.HashMap, .Map
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 of the org.codehaus.groovy.vmplugin.v7 package of groovy-core.

widenOperatorsback to summary
private static MethodType widenOperators(MethodType mt)

Widens the operators. For math operations like a+b we generally execute them using a conversion to certain types. If a for example is an int and b a byte, we do the operation using integer math. This method gives a simplified MethodType that contains the two operators with this widening according to Groovy rules applied. That means both parameters in the MethodType will have the same type.
