Class MathContext
 Serializable
Immutable objects describing settings such as rounding mode and digit
precision for numerical operations such as those in the BigDecimal class.
static MathContext  DECIMAL128  A MathContext for the IEEE 754R Decimal128 format  34 digit preicision and
HALF_EVEN rounding.

static MathContext  DECIMAL32  A MathContext for the IEEE 754R Decimal32 format  7 digit preicision and
HALF_EVEN rounding.

static MathContext  DECIMAL64  A MathContext for the IEEE 754R Decimal64 format  16 digit preicision and
HALF_EVEN rounding.

static MathContext  UNLIMITED  A MathContext for unlimited precision arithmetic *

MathContext(int setPrecision)  Constructs a new MathContext with the specified precision and with HALF_UP
rounding.

MathContext(int setPrecision, RoundingMode setRoundingMode)  Constructs a new MathContext with the specified precision and rounding
mode.

MathContext(String val)  Constructs a MathContext from a String that has the same form as one
produced by the toString() method.

boolean  equals(Object x)  Returns true if x is a MathContext and has the same precision setting
and rounding mode as this MathContext.

int  getPrecision()  Returns the precision setting.

RoundingMode  getRoundingMode()  Returns the rounding mode setting.

int  hashCode()  Returns the hashcode for this MathContext.

String  toString()  Returns "precision=p roundingMode=MODE" where p is an int giving the
precision and MODE is UP, DOWN, HALF_UP, HALF_DOWN, HALF_EVEN, CEILING,
FLOOR, or UNNECESSARY corresponding to rounding modes.
