- the Decimal128 value representing the given String
- Throws:
NumberFormatException
- if the value is out of the Decimal128 range- See Also:
- From-String Specification
-
fromIEEE754BIDEncoding
public static Decimal128 fromIEEE754BIDEncoding(long high, long low)
Create an instance with the given high and low order bits representing this Decimal128 as an IEEE 754-2008 128-bit decimal floating point using the BID encoding scheme.- Parameters:
high
- the high-order 64 bitslow
- the low-order 64 bits- Returns:
- the Decimal128 value representing the given high and low order bits
-
getHigh
public long getHigh()
Gets the high-order 64 bits of the IEEE 754-2008 128-bit decimal floating point encoding for this Decimal128, using the BID encoding scheme.- Returns:
- the high-order 64 bits of this Decimal128
-
getLow
public long getLow()
Gets the low-order 64 bits of the IEEE 754-2008 128-bit decimal floating point encoding for this Decimal128, using the BID encoding scheme.- Returns:
- the low-order 64 bits of this Decimal128
-
bigDecimalValue
public BigDecimal bigDecimalValue()
Gets a BigDecimal that is equivalent to this Decimal128.- Returns:
- a BigDecimal that is equivalent to this Decimal128
- Throws:
ArithmeticException
- if the Decimal128 value is NaN, Infinity, -Infinity, or -0, none of which can be represented as a BigDecimal
-
isNegative
public boolean isNegative()
Returns true if this Decimal128 is negative.- Returns:
- true if this Decimal128 is negative
-
isInfinite
public boolean isInfinite()
Returns true if this Decimal128 is infinite.- Returns:
- true if this Decimal128 is infinite
-
isFinite
public boolean isFinite()
Returns true if this Decimal128 is finite.- Returns:
- true if this Decimal128 is finite
-
isNaN
public boolean isNaN()
Returns true if this Decimal128 is Not-A-Number (NaN).- Returns:
- true if this Decimal128 is Not-A-Number
-
compareTo
public int compareTo(Decimal128 o)
- Specified by:
compareTo
in interfaceComparable<Decimal128>
-
intValue
public int intValue()
Converts thisDecimal128
to aint
. This conversion is analogous to the narrowing primitive conversion fromdouble
toint
as defined in The JavaTM Language Specification: any fractional part of thisDecimal128
will be discarded, and if the resulting integral value is too big to fit in aint
, only the low-order 32 bits are returned. Note that this conversion can lose information about the overall magnitude and precision of thisDecimal128
value as well as return a result with the opposite sign. Note that#NEGATIVE_ZERO
is converted to0
.
-
longValue
public long longValue()
Converts thisDecimal128
to along
. This conversion is analogous to the narrowing primitive conversion fromdouble
tolong
as defined in The JavaTM Language Specification: any fractional part of thisDecimal128
will be discarded, and if the resulting integral value is too big to fit in along
, only the low-order 64 bits are returned. Note that this conversion can lose information about the overall magnitude and precision of thisDecimal128
value as well as return a result with the opposite sign. Note that#NEGATIVE_ZERO
is converted to0L
.
-
floatValue
public float floatValue()
Converts thisDecimal128
to afloat
. This conversion is similar to the narrowing primitive conversion fromdouble
tofloat
as defined in The JavaTM Language Specification: if thisDecimal128
has too great a magnitude to represent as afloat
, it will be converted toFloat.NEGATIVE_INFINITY
orFloat.POSITIVE_INFINITY
as appropriate. Note that even when the return value is finite, this conversion can lose information about the precision of theDecimal128
value. Note that#NEGATIVE_ZERO
is converted to0.0f
.- Specified by:
floatValue
in classNumber
- Returns:
- this
Decimal128
converted to afloat
. - Since:
- 3.10
-
doubleValue
public double doubleValue()
Converts thisDecimal128
to adouble
. This conversion is similar to the narrowing primitive conversion fromdouble
tofloat
as defined in The JavaTM Language Specification: if thisDecimal128
has too great a magnitude to represent as adouble
, it will be converted toDouble.NEGATIVE_INFINITY
orDouble.POSITIVE_INFINITY
as appropriate. Note that even when the return value is finite, this conversion can lose information about the precision of theDecimal128
value. Note that#NEGATIVE_ZERO
is converted to0.0d
.- Specified by:
doubleValue
in classNumber
- Returns:
- this
Decimal128
converted to adouble
. - Since:
- 3.10
-
equals
public boolean equals(Object o)
Returns true if the encoded representation of this instance is the same as the encoded representation ofo
.One consequence is that, whereas
Double.NaN != Double.NaN
,new Decimal128("NaN").equals(new Decimal128("NaN")
returns true.Another consequence is that, as with BigDecimal,
new Decimal128("1.0").equals(new Decimal128("1.00")
returns false, because the precision is not the same and therefore the representation is not the same.
-
toString
public String toString()
Returns the String representation of the Decimal128 value.- Overrides:
toString
in classObject
- Returns:
- the String representation
