Java java.lang Float fields, constructors, methods, implement or subclass

Introduction

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

The text is from its open source code.

Field

float	POSITIVE_INFINITY A constant holding the positive infinity of type float .
float	NEGATIVE_INFINITY A constant holding the negative infinity of type float .
float	NaN A constant holding a Not-a-Number (NaN) value of type float .
float	MAX_VALUE A constant holding the largest positive finite value of type float , (2-2^-23)·2¹²⁷.
float	MIN_NORMAL A constant holding the smallest positive normal value of type float , 2^-126.
float	MIN_VALUE A constant holding the smallest positive nonzero value of type float , 2^-149.
int	MAX_EXPONENT Maximum exponent a finite float variable may have.
int	MIN_EXPONENT Minimum exponent a normalized float variable may have.
int	SIZE The number of bits used to represent a float value.
int	BYTES The number of bytes used to represent a float value.
Class	TYPE The Class instance representing the primitive type float .

Constructor

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

Method

byte	byteValue() Returns the value of this Float as a byte after a narrowing primitive conversion.
int	compare(float f1, float f2) Compares the two specified float values.
int	compareTo(Float anotherFloat) Compares two Float objects numerically.
double	doubleValue() Returns the value of this Float as a double after a widening primitive conversion.
boolean	equals(Object obj) Compares this object against the specified object.
int	floatToIntBits(float value) Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout.
int	floatToRawIntBits(float value) Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout, preserving Not-a-Number (NaN) values.
float	floatValue() Returns the float value of this Float object.
Class	getClass() Returns the runtime class of this Object .
int	hashCode() Returns a hash code for this Float object.
int	hashCode(float value) Returns a hash code for a float value; compatible with Float.hashCode() .
float	intBitsToFloat(int bits) Returns the float value corresponding to a given bit representation.
int	intValue() Returns the value of this Float as an int after a narrowing primitive conversion.
boolean	isFinite(float f) 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 Float value is infinitely large in magnitude, false otherwise.
boolean	isInfinite(float v) Returns true if the specified number is infinitely large in magnitude, false otherwise.
boolean	isNaN() Returns true if this Float value is a Not-a-Number (NaN), false otherwise.
boolean	isNaN(float v) Returns true if the specified number is a Not-a-Number (NaN) value, false otherwise.
long	longValue() Returns value of this Float as a long after a narrowing primitive conversion.
float	max(float a, float b) Returns the greater of two float values as if by calling Math#max(float,float) Math.max .
float	parseFloat(String s) Returns a new float initialized to the value represented by the specified String , as performed by the valueOf method of class Float .
short	shortValue() Returns the value of this Float as a short after a narrowing primitive conversion.
String	toHexString(float f) Returns a hexadecimal string representation of the float argument.
String	toString() Returns a string representation of this Float object.
String	toString(float f) Returns a string representation of the float argument.
Float	valueOf(String s) Returns a Float object holding the float value represented by the argument string s .
Float	valueOf(float f) Returns a Float instance representing the specified float value.
