Numeric.isInteger - check if the value stored in the Numeric is an integer
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:" );
n = (Numeric)engine.evaluate( "2^30:" );
n = (Numeric)engine.evaluate( "2^62:" );
n = (Numeric)engine.evaluate( "2^80:" );
n = (Numeric)engine.evaluate( "10.:" );
}
Executing this code produces the following output.
true
false
