OtpErlangFloat

public class OtpErlangDouble

extends OtpErlangObject

implements java.io.Serializable, java.lang.Cloneable

Provides a Java representation of Erlang floats and doubles. Erlang defines only one floating point numeric type, however this class and its subclass OtpErlangFloat are used to provide representations corresponding to the Java types Double and Float.

Constructor Detail

OtpErlangDouble

public OtpErlangDouble(double d)

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 OtpErlangRangeException

Get 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.

Overrides:

toString in class OtpErlangObject

Returns:

the string representation of this double.

encode

public void encode(OtpOutputStream buf)

Convert this double to the equivalent Erlang external representation.

Overrides:

encode in class OtpErlangObject

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.

Overrides:

equals in class OtpErlangObject

Parameters:

o - the float to compare to.

Returns:

true if the floats have the same value.
