Description

{

    public static void main( String notused[] ) throws MapleException

    {

        String[] mapleArgs = { "java" };

        Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );

        Numeric n = (Numeric)engine.evaluate( "2^33:" );

        System.out.println( n.isInt() );

        try

        {

            n.intValue();

        }

        catch ( MapleException me )

        {

            System.out.println( me.getMessage() );

        }

        n = (Numeric)engine.evaluate( "2^20:" );

        System.out.println( n.isInt() );

        int i = n.intValue();

        System.out.println( i );

    }
