Class MathContext
- Serializable
Immutable objects describing settings such as rounding mode and digit
precision for numerical operations such as those in the BigDecimal class.
MathContext(int setPrecision) - Constructs a new MathContext with the specified precision and with HALF_UP
rounding.
|
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.
|
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.

MathContext
public MathContext(int setPrecision)
Constructs a new MathContext with the specified precision and with HALF_UP
rounding.
setPrecision
- the precision for the new MathContext
MathContext
public MathContext(String val)
Constructs a MathContext from a String that has the same form as one
produced by the toString() method.
equals
public boolean equals(Object x)
Returns true if x is a MathContext and has the same precision setting
and rounding mode as this MathContext.
- equals in interface Object
- true if the above conditions hold
getPrecision
public int getPrecision()
Returns the precision setting.
hashCode
public int hashCode()
Returns the hashcode for this MathContext.
- hashCode in interface Object
- the hashcode for this MathContext.
toString
public 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.
- toString in interface Object
- a String describing this MathContext
