Constant Field Values

value

public final double value

The double value.

Method Detail

id

public int id()

Specified by:

id in interface JsValue

compareTo

public int compareTo(JsDouble o)

Compares two JsDouble objects numerically.

Specified by:

compareTo in interface Comparable<JsDouble>

See Also:

Double.compareTo(Double)

equals

public boolean equals(@Nullable Object that)

Indicates whether some other object is "equal to" this json double. Numbers of different types are equals if the have the same value.

Overrides:

equals in class Object

Parameters:

that - the reference object with which to compare.

Returns:

true if that is a JsNumber with the same value as this JsDouble

hashCode

public int hashCode()

Returns the hashcode of this json double.

Overrides:

hashCode in class Object

Returns:

the hashcode of this JsDouble

map

public JsDouble map(DoubleUnaryOperator fn)

Maps this json double into another one.

Parameters:

fn - the mapping function

Returns:

a new JsDouble

minus

public JsDouble minus(JsDouble that)

subtract this long from the specified one

Parameters:

that - the specified long

Returns:

this long minus the specified one

of

public static JsDouble of(double n)

Static factory method to create a JsDouble from a double primitive type.

Parameters:

n - the double primitive type

Returns:

a new JsDouble

plus

public JsDouble plus(JsDouble that)

adds up this long to the specified one

Parameters:

that - the specified long

Returns:

the sum of both longs

test

public boolean test(DoublePredicate predicate)

Tests the value of this json double on a predicate.

Parameters:

predicate - the predicate

Returns:

true if this double satisfies the predicate

times

public JsDouble times(JsDouble that)

multiplies this long by the specified one

Parameters:

that - the specified long

Returns:

this long times the specified one

toString

public String toString()

Overrides:

toString in class Object

Returns:

a string representation of this object.

See Also:

Double.toString

bigIntegerExact

public Optional<BigInteger> bigIntegerExact()

Converts this double to a BigInteger, checking for lost information. An empty optional is returned if this double has a nonzero fractional part.

Returns:

this double as an bigint wrapped in an Optional

equals

public boolean equals(JsBigDec jsBigDec)

returns true if this double and the specified bigdecimal represent the same number

Parameters:

jsBigDec - the specified JsBigDec

Returns:

true if both JsElem are the same value

equals

public boolean equals(JsBigInt jsBigInt)

returns true if this double and the specified biginteger represent the same number

Parameters:

jsBigInt - the specified JsBigInt

Returns:

true if both JsElem are the same value

equals

public boolean equals(JsLong jsLong)

returns true if this double and the specified long represent the same number

Parameters:

jsLong - the specified JsLong

Returns:

true if both JsElem are the same value

equals

public boolean equals(JsInt jsInt)

returns true if this double and the specified integer represent the same number

Parameters:

jsInt - the specified JsInt

Returns:

true if both JsElem are the same value

isDouble

public boolean isDouble()

Specified by:

isDouble in interface JsValue

Returns:

true if this JsElem is a JsDouble

isNumber

public boolean isNumber()

Specified by:

isNumber in interface JsValue

Returns:

true if this element is a number
