to create from a BigDecimal., to create from a BigInteger., to create from a double, to create from a float., to create from a long., to create from a short., to create from an integer., to create from a Stringl, Thus by doing this, this class is able to preserve arbitrary precison of any given number. If {@link SdkNumber} is expected in a particular number format then its corresponding getter methods can be used. Example for a {@link SdkNumber} created with {@link BigDecimal} the, can be used., Serialized Form

Method Detail

fromInteger

public static SdkNumber fromInteger(int integerValue)

Create SdkNumber from a integer value.

Parameters:

integerValue - Integer value.

Returns:

new SdkNumber for the given int value.

fromBigInteger

public static SdkNumber fromBigInteger(BigInteger bigIntegerValue)

Create SdkNumber from a BigInteger value.

Parameters:

bigIntegerValue - BigInteger value.

Returns:

new SdkNumber for the given BigInteger value.

fromBigDecimal

public static SdkNumber fromBigDecimal(BigDecimal bigDecimalValue)

Create SdkNumber from a BigDecimal value.

Parameters:

bigDecimalValue - BigInteger value.

Returns:

new SdkNumber for the given BigDecimal value.

fromLong

public static SdkNumber fromLong(long longValue)

Create SdkNumber from a long Value.

Parameters:

longValue - long value.

Returns:

new SdkNumber for the given long value.

fromDouble

public static SdkNumber fromDouble(double doubleValue)

Create SdkNumber from a double Value.

Parameters:

doubleValue - long value.

Returns:

new SdkNumber for the given double value.

fromShort

public static SdkNumber fromShort(short shortValue)

Create SdkNumber from a long Value.

Parameters:

shortValue - long value.

Returns:

new SdkNumber for the given long value.

fromFloat

public static SdkNumber fromFloat(float floatValue)

Create SdkNumber from a float Value.

Parameters:

floatValue - float value.

Returns:

new SdkNumber for the given float value.

fromString

public static SdkNumber fromString(String stringValue)

Create SdkNumber from a long Value.

Parameters:

stringValue - String value.

Returns:

new SdkNumber for the given stringValue value.

intValue

public int intValue()

Gets the integer value of the SdkNumber. If we do a intValue() for SdkNumber constructed from float, double, long, BigDecimal, BigInteger number type then it may result in loss of magnitude and a loss of precision. The result may lose some of the least significant bits of the value. Precision is not lost while getting a SdkNumber which was constructed as lower precision number type like short, byte, integer.

Specified by:

intValue in class Number

Returns:

integer value of SdkNumber .

longValue

public long longValue()

Gets the long value of the SdkNumber. If we do a longValue() for SdkNumber constructed from float, double, BigDecimal, BigInteger number type then it may result in loss of magnitude and a loss of precision. Precision is not lost while getting a SdkNumber which was constructed from lower precision type like short, byte, integer.

Specified by:

longValue in class Number

Returns:

long value of SdkNumber.

floatValue

public float floatValue()

Gets the float value of the SdkNumber. If we do a floatValue() for SdkNumber constructed from double, BigDecimal, BigInteger number type then it may result in loss of magnitude and a loss of precision. Precision is not lost while getting a SdkNumber which was constructed from precision type like short, byte, integer, long.

Specified by:

floatValue in class Number

Returns:

long value of SdkNumber.

doubleValue

public double doubleValue()

Gets the double value of the SdkNumber. If we do a doubleValue() for SdkNumber constructed from BigDecimal, BigInteger number type then it may result in loss of magnitude and a loss of precision. Precision is not lost while getting a SdkNumber which was constructed from precision type like short, byte, integer, long, float.

Specified by:

doubleValue in class Number

Returns:

long value of SdkNumber.

bigDecimalValue

public BigDecimal bigDecimalValue()

Gets the bigDecimalValue of the SdkNumber. Precision is not lost in this case. However bigDecimalValue cannot be performed on a {SdkNumber} constructed from Float/Double Nan/Infinity.

Returns:

BigDecimal value of SdkNumber

Throws:

NumberFormatException - Exception in thrown if a SdkNumber was constructed asNan/Infinte number of Double/FLoat type.Since we cannot convert NaN/Infinite numbers to BigDecimal.

stringValue

public String stringValue()

Gets the String value of the SdkNumber.

Returns:

the stringValue

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
