Method Detail- 
parseBytespublic static Decimal64 parseBytes(byte[] decBytes) Parses the provided byte array to aDecimal64.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:
- java.lang.IllegalArgumentException- When- decBytesis not 8 bytes long
 
 - 
valueOfpublic static Decimal64 valueOf(java.math.BigDecimal value) Creates aDecimal64fromvalue, 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
 
 - 
valueOfpublic static Decimal64 valueOf(java.math.BigDecimal value, OverflowHandling overflowHandling) Creates aDecimal64fromvalue, 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_EXCEPTIONand the value is out of range.
 
 - 
valueOfpublic static Decimal64 valueOf(java.math.BigInteger value) Creates aDecimal64fromvalue, 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
 
 - 
valueOfpublic static Decimal64 valueOf(java.math.BigInteger value, OverflowHandling overflowHandling) Creates aDecimal64fromvalue, 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_EXCEPTIONand the value is out of range.
- See Also:
- valueOfExact(BigInteger)
 
 - 
valueOfExactpublic static Decimal64 valueOfExact(java.math.BigInteger value) Creates aDecimal64fromvalue, 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)
 
 - 
valueOfpublic static Decimal64 valueOf(double value) Creates aDecimal64fromvalue, applying rounding where necessary.Double.NaNis 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
 
 - 
valueOfpublic static Decimal64 valueOf(double value, OverflowHandling overflowHandling) Creates aDecimal64fromvalue, applying rounding where necessary.Double.NaNis 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_EXCEPTIONand the value is out of range.
 
 - 
valueOfpublic static Decimal64 valueOf(Decimal<?> decimal) Converts a decimal to Decimal64.For normal, finite, decimals, this behaves like valueOf(decimal.toBigDecimal()), seevalueOf(BigDecimal).- Parameters:
- decimal- Decimal to convert
- Returns:
- Decimal converted to Decimal64, or decimalitself if it already is Decimal64
 
 - 
valueOfpublic static Decimal64 valueOf(Decimal<?> decimal, OverflowHandling overflowHandling) Converts a decimal to Decimal64.For normal, finite, decimals, this behaves like valueOf(decimal.toBigDecimal(), overflowHandling), seevalueOf(BigDecimal, OverflowHandling).- Parameters:
- decimal- Decimal to convert
- overflowHandling- Overflow handling to apply
- Returns:
- Decimal converted to Decimal64, or decimalitself if it already is Decimal64
- Throws:
- DecimalOverflowException- If- OverflowHandling#THROW_EXCEPTIONand the value is out of range.
 
 - 
valueOfpublic static Decimal64 valueOf(java.lang.String value) Creates aDecimal64fromvalue, 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:
- java.lang.NumberFormatException- If the provided string is not valid numeric string.

- value- String value to convert
- overflowHandling- Overflow handling to apply
- Returns:
- Decimal equivalent
- Throws:
- java.lang.NumberFormatException- If the provided string is not valid numeric string.
- DecimalOverflowException- If- OverflowHandling#THROW_EXCEPTIONand the value is out of range.
