Double

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

Constant for the maximum double value, (2 - 2^-52) * 2¹⁰²³.

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

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

Constant for the minimum double value, 2^-1074.

Constant for the negative infinity value of the double type.

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

Constant for the positive infinity value of the double type.

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

The Class object that represents the primitive type double.

Constructs a new Double with the specified primitive double value.

Constructs a new Double 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 double values. There are two special cases:

• Double.NaN is equal to Double.NaN and it is greater than any other double value, including Double.POSITIVE_INFINITY;
• +0.0d is greater than -0.0d

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

• Double.NaN is equal to Double.NaN and it is greater than any other double value, including Double.POSITIVE_INFINITY;
• +0.0d is greater than -0.0d

Returns an integer corresponding to the bits of the given IEEE 754 double precision value. All Not-a-Number (NaN) values are converted to a single NaN representation (0x7ff8000000000000L) (compare to doubleToRawLongBits(double)).

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

Gets the primitive value of this double.

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

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

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

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 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 double 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 double is a Not-a-Number (NaN) value.

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

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 double 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 double into its hexadecimal string representation.

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

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.

Parses the specified string as a double value.

Returns a Double instance for the specified double value.
