class Example
{
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( "200:" );
System.out.println( n.isByte() );
try
n.byteValue();
}
catch ( MapleException me )
System.out.println( me.getMessage() );
n = (Numeric)engine.evaluate( "100:" );
byte b = n.byteValue();
System.out.println( b );
Executing this code produces the following output.
false
Error, value too large for integer[1]
true
100
