public class OtpErlangDouble extends OtpErlangObject
Provides a Java representation of Erlang floats and doubles. Erlang defines only one floating point numeric type, however this class and its subclassOtpErlangFloatare used to provide representations corresponding to the Java types Double and Float.- See Also:

Create an Erlang float from the given double value.
-
OtpErlangDouble
public OtpErlangDouble(OtpInputStream buf) throws OtpErlangDecodeException
Create an Erlang float from a stream containing a double encoded in Erlang external format.- Parameters:
buf- the stream containing the encoded value.- Throws:
OtpErlangDecodeException- if the buffer does not contain a valid external representation of an Erlang float.

Method Detail
-
doubleValue
public double doubleValue()
Get the value, as a double.- Returns:
- the value of this object, as a double.
-
floatValue
public float floatValue() throws OtpErlangRangeExceptionGet the value, as a float.- Returns:
- the value of this object, as a float.
- Throws:
OtpErlangRangeException- if the value cannot be represented as a float.
-
toString
public java.lang.String toString()
Get the string representation of this double.- Specified by:
toStringin classOtpErlangObject- Returns:
- the string representation of this double.
-
encode
public void encode(OtpOutputStream buf)
Convert this double to the equivalent Erlang external representation.- Specified by:
encodein classOtpErlangObject- Parameters:
buf- an output stream to which the encoded value should be written.
-
equals
public boolean equals(java.lang.Object o)
Determine if two floats are equal. Floats are equal if they contain the same value.- Specified by:
equalsin classOtpErlangObject- Parameters:
o- the float to compare to.- Returns:
- true if the floats have the same value.
