Constructor Summary | |
---|---|
MutableFloat()
Constructs a new MutableFloat with the default value of zero. | |
MutableFloat(float value)
Constructs a new MutableFloat with the specified value.
| |
MutableFloat(Number value)
Constructs a new MutableFloat with the specified value.
|
Method Summary | |
---|---|
int | compareTo(Object obj)
Compares this mutable to another in ascending order.
|
double | doubleValue()
Returns the value of this MutableFloat as a double.
|
boolean | equals(Object obj)
Compares this object against some other object. |
float | floatValue()
Returns the value of this MutableFloat as a float.
|
Object | getValue()
Gets the value as a Float instance.
|
int | hashCode()
Returns a suitable hashcode for this mutable.
|
int | intValue()
Returns the value of this MutableFloat as a int.
|
boolean | isInfinite()
Checks whether the float value is infinite.
|
boolean | isNaN()
Checks whether the float value is the special NaN value.
|
long | longValue()
Returns the value of this MutableFloat as a long.
|
void | setValue(float value)
Sets the value.
|
void | setValue(Object value)
Sets the value from any Number instance.
|
String | toString()
Returns the String value of this mutable.
|
Parameters: value a value.
Parameters: value a value.
Throws: NullPointerException if the object is null
Parameters: obj the mutable to compare to
Returns: negative if this is less, zero if equal, positive if greater
Returns: the numeric value represented by this object after conversion to type double.
true
if and only if the argument is
not null
and is a Float
object that represents a float
that has the
identical bit pattern to the bit pattern of the float
represented by this object. For this
purpose, two float values are considered to be the same if and only if the method
{@link Float#floatToIntBits(float)}returns the same int value when applied to each.
Note that in most cases, for two instances of class Float
,f1
and f2
,
the value of f1.equals(f2)
is true
if and only if
f1.floatValue() == f2.floatValue()
also has the value true
. However, there are two exceptions:
f1
and f2
both represent Float.NaN
, then the
equals
method returns true
, even though Float.NaN==Float.NaN
has
the value false
.
f1
represents +0.0f
while f2
represents -0.0f
,
or vice versa, the equal
test has the value false
, even though
0.0f==-0.0f
has the value true
.
Parameters: obj the object to be compared
Returns: true
if the objects are the same; false
otherwise.

Parameters: value the value to set
Parameters: value the value to set

Returns: the mutable value as a string
