Float class Methods in Java

java.lang.Float

The Float class wraps a value of primitive type float in an object. An object of type Float contains a single field whose type is float. In addition, this class provides several methods for converting a float to a String and a String to the float, as well as other constants and methods useful when dealing with the float.

Some methods of Float class

Float.BYTES: The number of bytes is used to represent a float value (i.e. 4).

Float.compare(): It compares the two specified float values.

Float.floatToIntBits(): It returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout.

Float.floatToRawIntBits(): It returns a representation of the specified floating-point value according to the IEEE 754 floating-point "single format" bit layout, preserving Not-a-Number (NaN) values.

Float.hashCode(): It returns a hash code for a float value.

Float.intBitsToFloat(): It returns the float value corresponding to a given bit representation.

Float.isFinite(): It returns true if the argument is a finite floating-point value; returns false otherwise (for NaN and infinity arguments).

Float.isInfinite():  It returns true if the specified number is infinitely large in magnitude, false otherwise.

Float.isNaN(): It returns true if the specified number is a Not-a-Number (NaN) value, false otherwise.

Float.max(): It returns the greater of two float values.

Float.MAX_EXPONENT: Maximum exponent a finite float variable may have.

Float.MAX_VALUE: A constant holding the largest positive finite value of type float (i.e 3.4028235E38).

Float.min(): It returns the smaller of two float values.

Float.MIN_EXPONENT: Minimum exponent a normalized float variable may have (i.e. -126).

Float.MIN_NORMAL: A constant holding the smallest positive normal value of type float (i.e. 1.17549435E-38).

Float.NaN: A constant holding a Not-a-Number (NaN) value of type float (i.e. NaN)

Float.NEGATIVE_INFINITY: A constant holding the negative infinity of type float (i.e -Infinity).

Float.parseFloat(): It returns a new float initialized to the value represented by the specified String, as performed by the valueOf method of class Float.

Float.POSITIVE_INFINITY: A constant holding the positive infinity of type float (i.e. Infinity).

Float.SIZE: The number of bits used to represent a float value (i.e 32).

Float.sum(): It adds two float values together as per the + operator.

Float.toHexString(): It returns a hexadecimal string representation of the float argument.

Float.toString(): It returns a string representation of the float argument.

Float.valueOf(float f): It returns a Float instance representing the specified float value.

Float.valueOf(String s): It returns a Float object holding the float value represented by the argument string s.
