Field Detail

TAG

public static final Asn1Tag TAG
The TAG constant describes the universal tag for this data type (UNIVERSAL 9).


value

public transient double value
This public member variable is where the double value is stored. This is the value that is encoded when one of the encode methods is called. It is also where the decoded result is stored when a decode method is called.

Constructor Detail

Asn1Real

public Asn1Real()
The default constructor sets the double value to zero.


Asn1Real

public Asn1Real(double value_)
This constructor creates an REAL object from a double value.

Parameters:
value_ - double value

Asn1Real

public Asn1Real(boolean floatType)
