20.9.10

public boolean equals(Object obj)

The result is

true

 if and only if the argument is not

null

 and is a

Float

 object

that represents the same

float

 value as this

Float

 object. For this purpose, two

float

 values are considered to be the same if and only if the method

floatToIntBits

( 20.9.22) returns the same

int

 value when applied to each.

Note that even though the

==

 operator returns

false

 if both operands are NaN,

this

equals

 method will return

true

 if this

Float

 object and the argument are

both

Float

 objects that represent NaN. On the other hand, even though the

==

operator returns

true

 if one operand is positive zero and the other is negative

zero, this

equals

 method will return

false

 if this

Float

 object and the argument

represent zeroes of different sign. This definition allows hashtables to operate

properly.

Overrides the

equals

 method of

Object

 ( 20.1.3).

20.9.11

public int hashCode()

The result is the integer bit representation, exactly as produced by the method

floatToIntBits

 ( 20.9.22), of the primitive

float

 value represented by this

Float

 object.

Overrides the

hashCode

 method of

Object

 ( 20.1.4).

20.9.12

public int intValue()

The

float

 value represented by this

Float

 object is converted ( 5.1.3) to type

int

 and the result of the conversion is returned.

Overrides the

intValue

 method of

Number

 ( 20.6.1).

20.9.13

public long longValue()

The

float

 value represented by this

Float

 object is converted ( 5.1.3) to type

long

 and the result of the conversion is returned.

Overrides the

longValue

 method of

Number

 ( 20.6.2).

20.9.14

public float floatValue()

The

float

 value represented by this

Float

 object is returned.

Overrides the

floatValue

 method of

Number

 ( 20.6.3).
