Immutable objects which encapsulate the context settings which describe certain rules for numerical operators, such as those implemented by the BigDecimal class.

Attributes: RegisterAttribute

Implements: IJavaObject IJavaPeerable ISerializable IDisposable

Remarks

Immutable objects which encapsulate the context settings which describe certain rules for numerical operators, such as those implemented by the BigDecimal class.

The base-independent settings are: <ol> <li>precision: the number of digits to be used for an operation; results are rounded to this precision

<li>roundingMode: a RoundingMode object which specifies the algorithm to be used for rounding. </ol>

Constructors

MathContext(Int32, RoundingMode)	Constructs a new `MathContext` with a specified precision and rounding mode.
MathContext(Int32)	Constructs a new `MathContext` with the specified precision and the `RoundingMode#HALF_UP HALF_UP` rounding mode.
MathContext(String)	Constructs a new `MathContext` from a string.

Properties

Class	Returns the runtime class of this `Object`. (Inherited from Object)
Decimal128	A `MathContext` object with a precision setting matching the IEEE 754R Decimal128 format, 34 digits, and a rounding mode of `RoundingMode#HALF_EVEN HALF_EVEN`, the IEEE 754R default.
Decimal32	A `MathContext` object with a precision setting matching the IEEE 754R Decimal32 format, 7 digits, and a rounding mode of `RoundingMode#HALF_EVEN HALF_EVEN`, the IEEE 754R default.
Decimal64	A `MathContext` object with a precision setting matching the IEEE 754R Decimal64 format, 16 digits, and a rounding mode of `RoundingMode#HALF_EVEN HALF_EVEN`, the IEEE 754R default.
Handle	The handle to the underlying Android instance. (Inherited from Object)
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)
Precision	Returns the `precision` setting.
RoundingMode	Returns the roundingMode setting.
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code. (Inherited from Object)
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code. (Inherited from Object)
Unlimited	A `MathContext` object whose settings have the values required for unlimited precision arithmetic.

Methods

Clone()	Creates and returns a copy of this object. (Inherited from Object)
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
JavaFinalize()	Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)

Wait()	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
