public class Float
extends Object

Class to represent a float as an immutable object.

Field Summary

static float	MAX_VALUE Maximum non-inifinity value.
static float	MIN_VALUE Smallest positive value.
static float	NaN Not a number value.
static float	NEGATIVE_INFINITY Negative infinity.
static float	POSITIVE_INFINITY Positive infinity.

Constructor Summary

Float(float f)
Constructs a Float object.

Method Summary

static int	floatToRawIntBits(float value) Returns an int containing the bits that represent the specified float.
static float	intBitsToFloat(int bits) Returns the float represented by the bit in the specified int.
static boolean	isInfinite(float f) Checks if the float value specified is infinite.
boolean	isNaN() Checks if this Float is Not-a-Number (NaN).
static boolean	isNaN(float f) Checks if the float value specified is Not-a-Number (NaN).
