/**
 * The Holder for {@code Float}. For more information on
 * Holder files, see <a href="doc-files/generatedfiles.html#holder">
 * "Generated Files: Holder Files"</a>.<P>
 * A Holder class for a {@code float}
 * that is used to store "out" and "inout" parameters in IDL methods.
 * If an IDL method signature has an IDL {@code float} as an "out"
 * or "inout" parameter, the programmer must pass an instance of
 * {@code FloatHolder} as the corresponding
 * parameter in the method invocation; for "inout" parameters, the programmer
 * must also fill the "in" value to be sent to the server.
 * Before the method invocation returns, the ORB will fill in the
 * value corresponding to the "out" value returned from the server.
 * <P>
 * If {@code myFloatHolder} is an instance of {@code FloatHolder},
 * the value stored in its {@code value} field can be accessed with
 * {@code myFloatHolder.value}.

 * @since       JDK1.2
