public class ProperFractionFormat extends FractionFormat
Minus signs are only allowed in the whole
number part - i.e., "-3 1/2" is legitimate and denotes -7/2, but "-3 -1/2" is invalid and will
result in a ParseException.

public Fraction parse(String source, ParsePosition pos)
Fraction object. This method expects the string to be
formatted as a proper fraction. Minus signs are only allowed in the whole number part -
i.e., "-3 1/2" is legitimate and denotes -7/2, but "-3 -1/2" is invalid and will result in a
ParseException.
