The ASN.1 Base 10 REAL type is converted to a Java class that extends the Asn1Real10 run-time class. A base 10 real is specified in ASN.1 using a WITH COMPONENTS clause such as the following:

   REAL(WITH COMPONENTS {
      ...,
      base (10)
   })

It is also used for XSD decimal type specifications.

In this case, the real number is stored as a C# character string in the character string base class:

   public String mValue;

<name> ::= REAL (WITH COMPONENTS { base(10) })

<xsd:decimal>

   public class <name> : Asn1Real10 {
  public <name> () {
     base();
  }
  public <name> (String value_) {
     base (value_);
  }
}
