Calling Sequence

Description

Examples

Calling Sequence

boolean isShort() throws MapleException

Description

• 

The isShort function returns true if the value represented by the current Numeric object is an integer small enough to fit into a Java short. Otherwise, the isShort function returns  false.

• 

If isShort returns true, a call to one of shortValue, intValue or longValue completes without error.

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 = (Numeric)engine.evaluate( "2^18:" );

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

        try

        {

            n.shortValue();

        }

        catch ( MapleException me )

        {

            System.out.println( me.getMessage() );

        }

        n = (Numeric)engine.evaluate( "2^14:" );

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

        short s = n.shortValue();

        System.out.println( s );

    }

}

Executing this code produces the following output.

false

Error, value does not fit in integer[2]
