boolean isInt() throws MapleException

If isInt returns true, a call to one of intValue or longValue completes without error.

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:" );

catch ( MapleException me )
System.out.println( me.getMessage() );
n = (Numeric)engine.evaluate( "2^20:" );
int i = n.intValue();
System.out.println( i );
