- NumericFPNode
  
  public NumericFPNode()
Method Details
- asToken
  
  public final JsonToken asToken()
  
  Description copied from class: BaseJsonNode
  
  Method that can be used for efficient type detection when using stream abstraction for traversing nodes. Will return the first JsonToken that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)
  
  Specified by:
  
  asToken in interface TreeNode
  
  Specified by:
  
  asToken in class ValueNode
- isFloatingPointNumber
  
  public final boolean isFloatingPointNumber()
  
  Overrides:
  
  isFloatingPointNumber in class JsonNode
  
  Returns:
  
  True if this node represents a non-integral numeric JSON value
- canConvertToShort
  
  public final boolean canConvertToShort()
  
  Description copied from class: JsonNode
  
  Method that can be used to check whether this node is a numeric node (JsonNode.isNumber() would return true) AND can be converted without loss to short (that is, its value fits in Java's 16-bit signed integer type, short and if it is a floating-point number, it does not have fractional part).
  NOTE: this method does not consider possible value type conversion from non-number types like JSON String into Number; so even if this method returns false, it is possible that JsonNode.asShort() could still succeed.
  
  Specified by:
  
  canConvertToShort in class NumericNode
- canConvertToInt
  
  public final boolean canConvertToInt()
  
  Description copied from class: JsonNode
  
  Method that can be used to check whether this node is a numeric node (JsonNode.isNumber() would return true) AND can be converted without loss to int (that is, its value fits in Java's 32-bit signed integer type, int and if it is a floating-point number, it does not have fractional part).
  NOTE: this method does not consider possible value type conversion from non-number types like JSON String into Number; so even if this method returns false, it is possible that JsonNode.asInt() could still succeed.
  
  Specified by:
  
  canConvertToInt in class NumericNode
- canConvertToLong
  
  public final boolean canConvertToLong()
  
  Description copied from class: JsonNode
  
  Method that can be used to check whether this node is a numeric node (JsonNode.isNumber() would return true) AND can be converted without loss to long (that is, its value fits in Java's 64-bit signed integer type, long and if it is a floating-point number, it does not have fractional part).
  NOTE: this method does not consider possible value type conversion from non-number types like JSON String into Number; so even if this method returns false, it is possible that JsonNode.asLong() could still succeed.
  
  Specified by:
  
  canConvertToLong in class NumericNode
- canConvertToExactIntegral
  
  public final boolean canConvertToExactIntegral()

Latter part allows floating-point numbers (for which JsonNode.isFloatingPointNumber() returns true) that do not have fractional part. Note that "not-a-number" values of double and float will return false as they cannot be converted to matching integral representations.
  
  Overrides:

  JSON String that represents JSON Numbers ("stringified" numbers)
  
  JSON Null (converted to BigDecimal.ZERO))
  
  POJO nodes that contain Number values
  Specified by:
  
  asDecimal in class NumericNode
  
  Returns:
  
  BigDecimal value this node represents, if possible to accurately represent
- asDecimal
  
  public BigDecimal asDecimal(BigDecimal defaultValue)
  
  Description copied from class: JsonNode
  
  Method similar to JsonNode.asDecimal(), but that will return defaultValue if this node cannot be coerced to Java BigDecimal.
  
  Specified by:
  
  asDecimal in class NumericNode
  
  Returns:
  
  BigDecimal value this node represents, if possible to accurately represent; defaultValue otherwise
- asDecimalOpt
  
  public Optional<BigDecimal> asDecimalOpt()
  
  Description copied from class: JsonNode
  
  Method similar to JsonNode.asDecimal(), but that will return empty Optional (Optional.empty()) if this node cannot be coerced to BigDecimal.
  
  Specified by:
  
  asDecimalOpt in class NumericNode
  
  Returns:
  
  Java BigDecimal value this node represents, as Optional<BigDecimal>, if possible to accurately represent; Optional.empty() otherwise
- _asShortValueUnchecked
  
  protected abstract short _asShortValueUnchecked()
  
  Method for sub-classes to implement; returns the underlying value as a short without any checks (wrt NaN or value range), so caller must ensure validity prior to calling
- _asIntValueUnchecked
  
  protected abstract int _asIntValueUnchecked()
  
  Method for sub-classes to implement; returns the underlying value as a int without any checks (wrt NaN or value range), so caller must ensure validity prior to calling
- _asLongValueUnchecked
  
  protected abstract long _asLongValueUnchecked()
  
  Method for sub-classes to implement; returns the underlying value as a long without any checks (wrt NaN or value range), so caller must ensure validity prior to calling
- _asBigIntegerValueUnchecked
  
  protected abstract BigInteger _asBigIntegerValueUnchecked()
  
  Method for sub-classes to implement; returns the underlying value as a BigInteger without any checks (wrt NaN), so caller must ensure validity prior to calling
- _asDecimalValueUnchecked
  
  protected abstract BigDecimal _asDecimalValueUnchecked()
  
  Method for sub-classes to implement; returns the underlying value as a BigDecimal without any checks (wrt NaN), so caller must ensure validity prior to calling
- _hasFractionalPart
  
  protected abstract boolean _hasFractionalPart()
- _inShortRange
  
  protected abstract boolean _inShortRange()
- _inIntRange
  
  protected abstract boolean _inIntRange()
- _inLongRange
  
  protected abstract boolean _inLongRange()
