title: IntegerUtils and DoubleUtils in Apache Commons package
body: <p>I use the Apache Commons package extensively, especially the StringUtils, BooleanUtils, ObjectUtils, MapUtils classes and find them extremely helpful. I am wondering if there are classes such as IntegerUtils, DoubleUtils that provide a similar functionality for their respective wrapper classes (I do not find such classes in the Apache Commons package).</p>
  
  <p>Thanks,</p>
