Float

Maximum base-2 exponent that a finite value of the float type may have. Equal to Math.getExponent(Float.MAX_VALUE) .

Constant for the maximum float value, (2 - 2 ^-23 ) * 2 ¹²⁷ .

Minimum base-2 exponent that a normal value of the float type may have. Equal to Math.getExponent(Float.MIN_NORMAL) .

Constant for the smallest positive normal value of the float type.

Constant for the minimum float value, 2 ^-149 .

Constant for the negative infinity value of the float type.

Constant for the Not-a-Number (NaN) value of the float type.

Constant for the positive infinity value of the float type.

Constant for the number of bits needed to represent a float in two's complement form.

The Class object that represents the primitive type float .

Constructs a new Float with the specified primitive float value.

Constructs a new Float with the specified primitive double value.

Constructs a new Float from the specified string.

Returns this object's value as a byte. Might involve rounding and/or truncating the value, so it fits into a byte.

Compares the two specified float values. There are two special cases:

• Float.NaN is equal to Float.NaN and it is greater than any other float value, including Float.POSITIVE_INFINITY ;
• +0.0f is greater than -0.0f

Compares this object to the specified float object to determine their relative order. There are two special cases:

• Float.NaN is equal to Float.NaN and it is greater than any other float value, including Float.POSITIVE_INFINITY ;
• +0.0f is greater than -0.0f

Returns this object's value as a double. Might involve rounding.

Tests this double for equality with object . To be equal, object must be an instance of Float and floatToIntBits must give the same value for both objects.

Note that, unlike == , -0.0 and +0.0 compare unequal, and NaN s compare equal by this method.

Returns an integer corresponding to the bits of the given IEEE 754 single precision float value . All Not-a-Number (NaN) values are converted to a single NaN representation ( 0x7fc00000 ) (compare to floatToRawIntBits(float) ).

Returns an integer corresponding to the bits of the given IEEE 754 single precision float value . Not-a-Number (NaN) values are preserved (compare to floatToIntBits(float) ).

Gets the primitive value of this float.

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns the IEEE 754 single precision float corresponding to the given bits .

Returns this object's value as an int. Might involve rounding and/or truncating the value, so it fits into an int.

Indicates whether the specified float represents an infinite value.

Indicates whether this object represents an infinite value.

Indicates whether this object is a Not-a-Number (NaN) value.

Indicates whether the specified float is a Not-a-Number (NaN) value.

Returns this object's value as a long. Might involve rounding and/or truncating the value, so it fits into a long.

Parses the specified string as a float value.

Returns this object's value as a short. Might involve rounding and/or truncating the value, so it fits into a short.

Converts the specified float into its hexadecimal string representation.

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

          getClass().getName() + '@' + Integer.toHexString(hashCode())
         

See Writing a useful toString method if you intend implementing your own toString method.

Returns a string containing a concise, human-readable description of the specified float value.

Parses the specified string as a float value.

Returns a Float instance for the specified float value.
