Calling Sequence

boolean isInteger() throws MapleException

Description

• 

The isInteger function returns true if the value represented by the current Numeric object is an integer of any size. Otherwise, the isInteger function returns false.

• 

If isInteger returns false, the Numeric represents a floating-point value.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

    public static void main( String notused[] ) throws MapleException

    {

        String[] mapleArgs = { "java" };

        Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );

        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:" );

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

        n = (Numeric)engine.evaluate( "10.:" );

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

    }

}
