MathContext.DECIMAL64 in Java

MathContext.DECIMAL64: This is available in java.math.MathContext class of Java.

Syntax:

MathContext java.math.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.

Approach

Java

import java.math.MathContext;

public class MathContextDECIMAL64 {
    public static void main(String[] args) {

        System.out.println(MathContext.DECIMAL64);
    }
}

Output:

precision=16 roundingMode=HALF_EVEN

equals(Object): This method compares this MathContext with the specified Object for equality.

getPrecision(): This method returns the precision setting. This value is always non-negative.

getRoundingMode(): This method returns the roundingMode setting.

hashCode(): This method returns the hash code for this MathContext.

toString(): This method returns the string representation of this MathContext.

MathContext.UNLIMITED: A MathContext object whose settings have the values required for unlimited precision arithmetic.

MathContext(int): This method constructs a new MathContext with the specified precision and the HALF_UP rounding mode.

MathContext(String): This method constructs a new MathContext from a string. The string must be in the same format as that produced by the toString method.

MathContext(int, RoundingMode): This method constructs a new MathContext with a specified precision and rounding mode.
