Numeric n;

n = (Numeric)engine.evaluate( "2^6:" );

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

n = (Numeric)engine.evaluate( "2^14:" );

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

n = (Numeric)engine.evaluate( "2^30:" );

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

n = (Numeric)engine.evaluate( "2^62:" );

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

n = (Numeric)engine.evaluate( "2^80:" );
