Java.math.MathContext Class

Introduction

The java.math.MathContext class provides immutable objects which encapsulate the context settings and describes certain rules for numerical operators, such as those implemented by the BigDecimal class.

The base-independent settings are −

precision − the number of digits to be used for an operation; results are rounded to this precision.

roundingMode − a RoundingMode object which specifies the algorithm to be used for rounding.

Class declaration

Following is the declaration for java.math.MathContext class −

Field

Following are the fields for java.math.MathContext class −

static MathContext DECIMAL128 − A MathContext object with a precision setting matching the IEEE 754R Decimal128 format, 34 digits, and a rounding mode of HALF_EVEN, the IEEE 754R default.

static MathContext DECIMAL32 − A MathContext object with a precision setting matching the IEEE 754R Decimal32 format, 7 digits, and a rounding mode of HALF_EVEN, the IEEE 754R default.

static MathContext DECIMAL64 − A MathContext object with a precision setting matching the IEEE 754R Decimal64 format, 16 digits, and a rounding mode of HALF_EVEN, the IEEE 754R default.

static MathContext UNLIMITED − A MathContext object whose settings have the values required for unpmited precision arithmetic.
