20.7.10

public float floatValue()

The

int

 value represented by this

Integer

 object is converted ( 5.1.2) to type

float

 and the result of the conversion is returned.

Overrides the

floatValue

 method of

Number

 ( 20.6.3).

20.7.11

public double doubleValue()

The

int

 value represented by this

Integer

 object is converted ( 5.1.2) to type

double

 and the result of the conversion is returned.

Overrides the

doubleValue

 method of

Number

 ( 20.6.4).

20.7.12

public static String toString(int i)

The argument is converted to signed decimal representation and returned as a

string, exactly as if the argument and the radix

10

 were given as arguments to the

toString

 method that takes two arguments ( 20.7.13).

20.7.13

public static String toString(int i, int radix)

The first argument is converted to a signed representation in the radix specified by

the second argument; this representation is returned as a string.

If the

radix

 is smaller than

Character.MIN_RADIX

 ( 20.5.3) or larger than

Character.MAX_RADIX

 ( 20.5.4), then the value

10

 is used instead.

If the first argument is negative, the first character of the result will be the

character

 (

 \u002d 

). If the first argument is not negative, no sign character

appears in the result.

The remaining characters of the result represent the magnitude of the first

argument. If the magnitude is zero, it is represented by a single zero character

 0 

(

 \u0030 

); otherwise, the first character of the representation of the magnitude

will not be the zero character.The following ASCII characters are used as digits:

0123456789abcdefghijklmnopqrstuvwxyz

These are

 \u0030 

 through

 \u0039 

 and

 \u0061 

 through

 \u007a 

. If the

radix

 is

N

, then the first

N

 of these characters are used as radix 

N

 digits in the

order shown. Thus, the digits for hexadecimal (radix 16) are

0123456789abcdef

.

If uppercase letters are desired, the

toUpperCase

 method ( 20.12.36) of class

String

 may be called on the result:

Integer.toString(n, 16).toUpperCase()
