Float class wraps a value of type float in an object.

Field Summary

Type	Field	Summary
static int	MAX_EXPONENT	Maximum exponent a finite float.
static float	MAX_VALUE	Largest positive finite value of type float.
static int	MIN_EXPONENT	Minimum exponent a normalized float variable may have.
static float	MIN_NORMAL	Smallest positive normal value of type float.
static float	MIN_VALUE	Smallest positive nonzero value of type float.
static float	NaN	Not-a-Number (NaN) value of type float.
static float	NEGATIVE_INFINITY	Negative infinity of type float.
static float	POSITIVE_INFINITY	Positive infinity of type float.
static int	SIZE	The number of bits used to represent a float value.
static Class	TYPE	The Class instance representing the primitive type float.

Constructor	Summary
Float(double value)	Creates a Float from double-type value.
Float(float value)	Creates a Float for the float argument.
Float(String s)	Creates a Float from a float represented by the string.

Convert to byte, double, float, int, long and short

Return	Method	Summary
byte	byteValue()	Returns this float as a byte.
double	doubleValue()	Returns the double value.
float	floatValue()	Returns the float value.
int	intValue()	Returns this float as an int by casting to type int.
long	longValue()	Returns this float as a long.
short	shortValue()	Returns this float as a short by casting.

Compare two float objects

Return	Method	Summary
static int	compare(float f1, float f2)	Compares the two specified float values.
int	compareTo(Float anotherFloat)	Compares two Float objects numerically.
boolean	equals(Object obj)	Compares this object against the specified object.

Infinite and Not A Number

Return	Method	Summary
boolean	isInfinite()	Returns true if this Float value is infinitely large in magnitude, false otherwise.
static 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.
static boolean	isNaN(float v)	Returns true if the specified number is a Not-a-Number (NaN) value, false otherwise.

Convert float value to String value

Return	Method	Summary
static String	toHexString(float f)	Returns a hexadecimal string representation of the float argument.
String	toString()	Returns a string representation of this Float object.
static String	toString(float f)	Returns a string representation of the float argument.

Convert string value to float value

Return	Method	Summary
static float	parseFloat(String s)	Returns a new float initialized to the value represented by the specified String.
static Float	valueOf(float f)	Returns a Float instance representing the specified float value.
static Float	valueOf(String s)	Returns a Float object holding the float value represented by the argument string s.

Bit oriented

Return	Method	Summary
static int	floatToIntBits(float value)	Returns a representation of the specified floating-point value.
static int	floatToRawIntBits(float value)	Returns a representation of the specified floating-point value.
static float	intBitsToFloat(int bits)	Returns the float value corresponding to a given bit representation.
