If this work goes forward, analagous methods for the long and double types would be added.

For testing, for each method, I was thinking to compare the operation of the method as a method reference to a lambda with the intended functionality over a set of inputs. This would help guard against any typos in constructing the simple methods. For example, a set of int values like {Integer.MAX_VALUE, -3, -1, 0, 1, 2, 10, Integer.MAX_VALUE} would be able to discriminate between {+, -, *, /}, etc.
