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[];

    Engine engine;

    Numeric n;

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    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() );

    }
