> If an option has a negative numerical argument, the parser mistakes it for another option and throws an error. For example, consider:
> {{Argument numArg = aBuilder.withValidator(NumberValidator.getNumberInstance()).withMinimum(1).withMaximum(1).create();}}
> {{Option numOpt = oBuilder.withLongName("num").withArgument(numArg).create();}}
> {{Group options = gBuilder.withOption(numOpt).create();}}
> Then parsing {{--num -0.1}} results in:
> {{Unexpected -0.1 while processing --num}}
