      Work Description: garydgregory commented on issue #455: LANG-1484: Allow decimal point at the end of the String
URL: https://github.com/apache/commons-lang/pull/455#issuecomment-589957886
 
 
   Not a fan unless `testIsParsable` is updated to actually prove that something is parsable or not; for example, update:
   ```
           assertTrue( NumberUtils.isParsable("64") );
   ```
   to
   ```
           assertTrue( NumberUtils.isParsable("64") );
           Integer.parseInt("64");
   ```
