Introduction

In this page you can find the methods, fields and constructors for java.lang Double.

The text is from its open source code.

Field

double	POSITIVE_INFINITY A constant holding the positive infinity of type double .
double	NEGATIVE_INFINITY A constant holding the negative infinity of type double .

double	MAX_VALUE A constant holding the largest positive finite value of type double , (2-2^-52)·2¹⁰²³.
double	MIN_NORMAL A constant holding the smallest positive normal value of type double , 2^-1022.
double	MIN_VALUE A constant holding the smallest positive nonzero value of type double , 2^-1074.
int	MAX_EXPONENT Maximum exponent a finite double variable may have.
int	MIN_EXPONENT Minimum exponent a normalized double variable may have.
int	SIZE The number of bits used to represent a double value.
int	BYTES The number of bytes used to represent a double value.
Class	TYPE The Class instance representing the primitive type double .

Constructor

	Double(double value) Constructs a newly allocated Double object that represents the primitive double argument.
	Double(String s) Constructs a newly allocated Double object that represents the floating-point value of type double represented by the string.

Method

byte	byteValue() Returns the value of this Double as a byte after a narrowing primitive conversion.
int	compare(double d1, double d2) Compares the two specified double values.
int	compareTo(Double anotherDouble) Compares two Double objects numerically.
long	doubleToLongBits(double value) Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "double format" bit layout.
long	doubleToRawLongBits(double value) Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "double format" bit layout, preserving Not-a-Number (NaN) values.
double	doubleValue() Returns the double value of this Double object.
boolean	equals(Object obj) Compares this object against the specified object.
float	floatValue() Returns the value of this Double as a float after a narrowing primitive conversion.
Class	getClass() Returns the runtime class of this Object .
int	hashCode() Returns a hash code for this Double object.
int	hashCode(double value) Returns a hash code for a double value; compatible with Double.hashCode() .
int	intValue() Returns the value of this Double as an int after a narrowing primitive conversion.
boolean	isFinite(double d) Returns true if the argument is a finite floating-point value; returns false otherwise (for NaN and infinity arguments).
boolean	isInfinite() Returns true if this Double value is infinitely large in magnitude, false otherwise.
boolean	isInfinite(double v) Returns true if the specified number is infinitely large in magnitude, false otherwise.
boolean	isNaN() Returns true if this Double value is a Not-a-Number (NaN), false otherwise.
boolean	isNaN(double v) Returns true if the specified number is a Not-a-Number (NaN) value, false otherwise.
double	longBitsToDouble(long bits) Returns the double value corresponding to a given bit representation.
long	longValue() Returns the value of this Double as a long after a narrowing primitive conversion.
double	max(double a, double b) Returns the greater of two double values as if by calling Math#max(double,double) Math.max .
double	min(double a, double b) Returns the smaller of two double values as if by calling Math#min(double,double) Math.min .
double	parseDouble(String s) Returns a new double initialized to the value represented by the specified String , as performed by the valueOf method of class Double .
short	shortValue() Returns the value of this Double as a short after a narrowing primitive conversion.
double	sum(double a, double b) Adds two double values together as per the + operator.
String	toHexString(double d) Returns a hexadecimal string representation of the double argument.
String	toString() Returns a string representation of this Double object.
String	toString(double d) Returns a string representation of the double argument.
Double	valueOf(String s) Returns a Double object holding the double value represented by the argument string s .
Double	valueOf(double d) Returns a Double instance representing the specified double value.
