Marcos Truchado commented on LANG-674:
--------------------------------------

Hi

I was hit yesterday by this issue. As today the docummentation is:

--
public static boolean isNumber(String str)

Checks whether the String a valid Java number.

Valid numbers include hexadecimal marked with the 0x qualifier, scientific notation and numbers marked with a type qualifier (e.g. 123L).

It might be useful to add a hint warning about the use of locales and this class do not play well together. A NumberUtils that supports locale would be an excellent feature, play with parsing/unparsing requires ugly code taking care of checked exceptions and so on.
