java.math.BigInteger toBigInteger() throws MapleException
The toBigInteger function returns the value represented in the Numeric as a Java BigInteger.
The java.math.BigInteger format can represent arbitrary-precision integers. If the value is not an integer, an error is raised.
To determine if the value is an integer, use the isInteger function.

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( "2^66:" );
System.out.println( n );
System.out.println( n.isLong() );
BigInteger bd = n.toBigInteger();
System.out.println( bd );
}
Executing this code produces the following output.
