 • To determine if the value fits within a Java int, use the isInt function.

Examples

 import com.maplesoft.openmaple.*; import com.maplesoft.externalcall.MapleException; class Example { public static void main( String notused[] ) throws MapleException { String mapleArgs[]; Engine engine; Numeric n; int i; mapleArgs = new String[1]; mapleArgs[0] = "java"; engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null ); 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() ); i = n.intValue(); System.out.println( i ); } }
