This simple class represents a precision (number of significant digits) and a RoundingMode to be used in BigDecimal arithmetic. The constants are predefined MathContext objects that can be used to select unlimited precision arithmetic or to select specific operating modes that match decimal floating-point modes defined by the IEEE 754R standard.
