parse
public static Decimal128 parse(String value)
Returns a Decimal128 value representing the given String.- Parameters:
value- the Decimal128 value represented as a String- Returns:
- 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:
compareToin interfaceComparable<Decimal128>
-
intValue
public int intValue()
Converts thisDecimal128to aint. This conversion is analogous to the narrowing primitive conversion fromdoubletointas defined in The Java™ Language Specification: any fractional part of thisDecimal128will 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 thisDecimal128value as well as return a result with the opposite sign. Note that#NEGATIVE_ZEROis converted to0.
-
longValue
public long longValue()
Converts thisDecimal128to along. This conversion is analogous to the narrowing primitive conversion fromdoubletolongas defined in The Java™ Language Specification: any fractional part of thisDecimal128will 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 thisDecimal128value as well as return a result with the opposite sign. Note that#NEGATIVE_ZEROis converted to0L.
-
floatValue
public float floatValue()
Converts thisDecimal128to afloat. This conversion is similar to the narrowing primitive conversion fromdoubletofloatas defined in The Java™ Language Specification: if thisDecimal128has too great a magnitude to represent as afloat, it will be converted toFloat.NEGATIVE_INFINITYorFloat.POSITIVE_INFINITYas appropriate. Note that even when the return value is finite, this conversion can lose information about the precision of theDecimal128value. Note that#NEGATIVE_ZEROis converted to0.0f.- Specified by:
floatValuein classNumber- Returns:
- this
Decimal128converted to afloat. - Since:
- 3.10
-
doubleValue
public double doubleValue()
Converts thisDecimal128to adouble. This conversion is similar to the narrowing primitive conversion fromdoubletofloatas defined in The Java™ Language Specification: if thisDecimal128has too great a magnitude to represent as adouble, it will be converted toDouble.NEGATIVE_INFINITYorDouble.POSITIVE_INFINITYas appropriate. Note that even when the return value is finite, this conversion can lose information about the precision of theDecimal128value. Note that#NEGATIVE_ZEROis converted to0.0d.- Specified by:
doubleValuein classNumber- Returns:
- this
Decimal128converted 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:
toStringin classObject- Returns:
- the String representation
