Method Details

parseBytes

public static Decimal64 parseBytes(byte[] decBytes)

Parses the provided byte array to a Decimal64.

This method parses network byte-order (aka big-endian). When using little-endian order, you will need to reverse the bytes in the array first.

Parameters:

decBytes - Bytes of the Decimal64 value in network byte-order (aka big-endian)

Returns:

Instance of Decimal64

Throws:

IllegalArgumentException - When decBytes is not 8 bytes long

valueOf

public static Decimal64 valueOf(BigDecimal value)

Creates a Decimal64 from value, applying rounding where necessary.

Values exceeding the range of this type will be returned as +/-Infinity.

Parameters:

value - Big decimal value to convert

Returns:

Decimal64 equivalent

valueOf

public static Decimal64 valueOf(BigDecimal value,
 OverflowHandling overflowHandling)

Creates a Decimal64 from value, applying rounding where necessary.

Values exceeding the range of this type will be handled according to the specified overflow handling.

Parameters:

value - Big decimal value to convert

overflowHandling - Overflow handling to apply

Returns:

Decimal64 equivalent

Throws:

DecimalOverflowException - If OverflowHandling#THROW_EXCEPTION and the value is out of range.

valueOf

public static Decimal64 valueOf(BigInteger value)

Creates a Decimal64 from value, applying rounding where necessary.

Values exceeding the range of this type will be returned as +/-Infinity.

Parameters:

value - Big integer value to convert

Returns:

Decimal64 equivalent

valueOf

public static Decimal64 valueOf(BigInteger value,
 OverflowHandling overflowHandling)

Creates a Decimal64 from value, applying rounding where necessary.

Values exceeding the range of this type will be handled according to the specified overflow handling.

Calling this method is equivalent to valueOf(new BigDecimal(value), overflowHandling).

Parameters:

value - Big integer value to convert

overflowHandling - Handling of overflows

Returns:

Decimal64 equivalent

Throws:

DecimalOverflowException - If OverflowHandling#THROW_EXCEPTION and the value is out of range.

See Also:

• valueOfExact(BigInteger)

valueOfExact

public static Decimal64 valueOfExact(BigInteger value)

Creates a Decimal64 from value, rejecting values that would lose precision due to rounding.

Parameters:

value - Big integer value to convert

Returns:

Decimal64 equivalent

Throws:

DecimalOverflowException - If the value is out of range.

See Also:

• valueOf(BigInteger, OverflowHandling)

valueOf

public static Decimal64 valueOf(double value)

Creates a Decimal64 from value, applying rounding where necessary.

Double.NaN is mapped to positive NaN, the infinities to their equivalent +/- infinity.

For normal, finite, values, this is equivalent to valueOf(BigDecimal.valueOf(value)).

Parameters:

value - Double value

Returns:

Decimal equivalent

valueOf

public static Decimal64 valueOf(double value,
 OverflowHandling overflowHandling)

Creates a Decimal64 from value, applying rounding where necessary.

Double.NaN is mapped to positive NaN, the infinities to their equivalent +/- infinity.

For normal, finite, values, this is equivalent to valueOf(BigDecimal.valueOf(value), overflowHandling).

Parameters:

value - Double value

overflowHandling - Overflow handling to apply

Returns:

Decimal equivalent

Throws:

DecimalOverflowException - If OverflowHandling#THROW_EXCEPTION and the value is out of range.

valueOf

public static Decimal64 valueOf(Decimal<?> decimal)

Converts a decimal to Decimal64.

For normal, finite, decimals, this behaves like valueOf(decimal.toBigDecimal()), see valueOf(BigDecimal).

Parameters:

decimal - Decimal to convert

Returns:

Decimal converted to Decimal64, or decimal itself if it already is Decimal64

valueOf

public static Decimal64 valueOf(Decimal<?> decimal,
 OverflowHandling overflowHandling)

Converts a decimal to Decimal64.

For normal, finite, decimals, this behaves like valueOf(decimal.toBigDecimal(), overflowHandling), see valueOf(BigDecimal, OverflowHandling).

Parameters:

decimal - Decimal to convert

overflowHandling - Overflow handling to apply

Returns:

Decimal converted to Decimal64, or decimal itself if it already is Decimal64

Throws:

DecimalOverflowException - If OverflowHandling#THROW_EXCEPTION and the value is out of range.

valueOf

public static Decimal64 valueOf(String value)

Creates a Decimal64 from value, applying rounding where necessary.

Except for the special values [+/-]Inf, [+/-]Infinity, [+/-]NaN and [+/-]sNaN (case insensitive), the rules of BigDecimal(String) apply, with special handling in place to discern between positive and negative zero.

Values exceeding the range of this type will be returned as +/-Infinity.

Parameters:

value - String value to convert

Returns:

Decimal equivalent

Throws:

NumberFormatException - If the provided string is not valid numeric string.

valueOf

public static Decimal64 valueOf(String value,
 OverflowHandling overflowHandling)

Creates a Decimal64 from value, applying rounding where necessary.

Except for the special values [+/-]Inf, [+/-]Infinity, [+/-]NaN and [+/-]sNaN (case insensitive), the rules of BigDecimal(String) apply, with special handling in place to discern between positive and negative zero.

Values exceeding the range of this type will be handled according to the specified overflow handling.

Parameters:

value - String value to convert

overflowHandling - Overflow handling to apply

Returns:

Decimal equivalent

Throws:

NumberFormatException - If the provided string is not valid numeric string.

DecimalOverflowException - If OverflowHandling#THROW_EXCEPTION and the value is out of range.
