> It would be nice to have an {{isParseable}} method (or whatever it may be called), to be able to identify valid (=parseable) Numbers, something along the lines {{toDouble(String)}} / {{toLong(String)}} etc., but returning {{true}} / {{false}} while avoiding at the same time the {{try/catch(NumberFormatException)}} of those methods.
> This method would be similar to {{isNumber}}, but it should yield {{true}} for invalid octals like "018" which are parseable as Numbers. The point of this method is to identify "human" (neither hex nor octal, but should handle decimal points) numbers stored as Strings, 
> We are using NumberUtils#isNumber to identify valid (parseable, human) numbers, but as of 3.3, this method also handles octal numbers, so, f.ex.,  018, which was recognized as a valid number, isn't recognized anymore as one.
